STORY:

A group of elderly people are giving interviews about how they lived through the 1930s Great Depression in a climate with crop blight and constant dust. An elderly woman is the first to be observed, and she claims that her father was not born a farmer.

The setting shifts. Joe Cooper (Matthew McConaughey), a farmer and widower, is introduced to us. He is a school taught previous NASA aircraft tester and specialist who had to surrender his occupation to cultivate, living in an overview farmhouse, probably possessed by his father by marriage. They farm corn because wheat is no longer available and okra is just starting to disappear because of blight. We don't see any animals.

In eastern Colorado, the year is 2060. Famine has wiped out more than half of the world's population, and America has become a struggling agrarian society for the past 30 years. Since about 40 years ago, technology has stagnated; automobiles are no longer manufactured, and laptop computers are now considered luxuries. On the bright side, there are no more militaries or wars in the world. Kids are put through tests at a certain age to find out what jobs they will need to take to help humanity survive. In order to win the Cold War and send the United States to the moon in 1969, it is taught in school that the mission was a hoax.

Cooper's family comprises of his kid father by marriage, Donald (John Lithgow),15-year-old child Tom (Timothée Chalamet), and 10-year-old little girl Murph (Mackenzie Foy). Donald, who was born either at the end of the 20th century or at the beginning of the 21st, fondly recalls a time when technology was constantly evolving and new gadgets were developed. He is a genuine man who helps out around the house and gets along well with Cooper. In the evening, they talk about how things ought to be and the state of the world while sipping beer on the porch. Joe's child Tom is a kid of normal knowledge previously being precluded to be a rancher by the school organization, since an advanced degree is presently something just a tiny rate those will partake in the honor of. Murph, Cooper's feisty and highly intelligent daughter, is a close friend who shares his passion for space and science. She accepts her room is spooky by a phantom since books continue to tumble off her racks and a lunar boat model was simply pushed over.

The Cooper family enjoys a rare treat of attending a game of a supposedly major league baseball team at a local ball field similar to the one where Little League baseball is played today. They live a fairly simple life. His father-in-law is dissatisfied with the amateurism of the players and only has popcorn and no hot dogs for refreshments. They are brought back to the bleak world they live in by an approaching dust cloud, which interrupts the game and prematurely ends it. During the dust storm as the Cooper family returns to the farmhouse, Murph's bedroom did not have a window shut, and the dust settled perfectly on the floor. Cooper goes through the whole evening concentrating on the lines and Cooper thinks the lines are twofold code and facilitates for a spot he wants to find and uses a guide. He goes through the following day heading to the Rockies and his little girl slips into the truck to accompany him.

Cooper is apprehended and tasered into unconsciousness shortly after reaching his final destination, which is a gated, fenced-off area. Cooper wakes up in a room where TARS, a strange-looking robot, is questioning him. It turns out that Cooper is in a bunker—the world's best-kept secret—where he meets his former NASA boss, an Englishman by the name of Dr. John Brand (Michael Caine) and his lovely young daughter Amelia Brand (Anne Hathaway). Dr. Brand believes Cooper was brought there by a force, despite the fact that no one believes Cooper just stumbled into the location by accident. The remnants of NASA that reside in the facility secretly and are no longer funded by the government due to a lack of resources are what Cooper discovered to be the compound. A spacecraft is soon to depart for three potentially habitable planets, two of which orbit a supermassive black hole called Gargantua, via an unidentified wormhole near Saturn; a massive black sphere with a solar mass of approximately 50 million Earth suns and a diameter similar to that of the sun on Earth. Ten years earlier, 12 different ships carried 12 different astronauts through the wormhole. Only three of those ships—Miller, Mann, and Edmonds'—activated the thumbs up beacon, and they are all on three planets. Right now, NASA has no one to direct the space apparatus and without a second to spare they believe Cooper should go, regardless of his family obligations.

The bunker itself is, in fact, a centrifuge that is expected to change into something else in the future. The mission has two strategies: Plan A calls for putting the centrifuge in orbit like a space station and saving a lot of people; Dr. Brand must therefore solve the equation that will enable the researchers to defy gravity and launch the centrifuge into orbit. Plan B calls for repopulating the species by colonizing the most habitable of the three planets and freezing a lot of embryos. Dr. Brand guarantees Cooper the Earth is kicking the bucket and humankind doesn't have significantly longer and that he wants to guide the art and investigate, in case his family and the remainder of the world all bite the dust soon. Cooper is hesitant because he has only just left Earth's atmosphere, but Brand assures him that the twelve astronauts on the mission have never left the simulators.

The following day, Cooper and Murph return to the farmhouse, his little girl is incredibly angry with him for picking the mission. That evening, while Cooper and Donald are sipping beer on the porch, Donald is once more reminded by Cooper of the futility of staying and the conditions in which they live. Donald assures Cooper that he is acting in the right way, but he needs to make amends with Murph. The following morning, Cooper tries his best to console a weeping Murph and promises to come back to her. He also tells her that he might even be the same age when he returns, and he gives her a wristwatch so that she can see how much time has passed. Murph declines his confirmation and that her shelf is speaking with her in Morse Code to "remain". Cooper doesn't back down despite her pleas, and one more book falls before he leaves, but Cooper ignores it. Murph storms out the front door while Cooper is driving away to say his goodbyes to Tom and Donald. However, it is too late for Murph to catch up with Cooper.

Cooper, Amelia Brand, Dr. Doyle (Wes Bentley), Dr. Nikolai "Rom" Romilly (David Gyasi), and the TARS and CASE robots are aboard the space shuttle-like vehicle as it accelerates away from Earth. Two scientists, Doyle and Romilly, attended the meeting with Cooper in the NASA conference room. Everything suddenly quietens down, with the exception of the interior, when the spacecraft leaves the atmosphere. They dock with the ring-shaped Endurance, which has everything they need for space travel. They say their goodbyes to a spinning Earth as The Endurance departs, prepare for the lonely, confined, and potentially dangerous reality of space, and sleep in a water cryosleep bed covered in plastic for the two-year journey to Saturn.

Dr. Brand travels in Cooper's old Dodge Ram truck from 2010 to return it to the homestead and deliver a taped message to Cooper's family. Murph seems trusting her dad is home, however indignantly storms once more into the house. Donald informs Dr. Brand that Murph is making fools of her teachers, but Brand informs Donald that perhaps she will eventually make fools of him.

After two years.

The Perseverance is circling Saturn and Cooper is out of cryosleep, investigating video messages. His child Tom lets him know he's doing approve and Donald says greetings, advising Cooper that Murph actually will not converse with him. The wormhole, which resembles a plasma globe and will serve as a quick route to the three planets in the next galaxy, is discovered by the Endurance crew. The team take off for the harsh ride, (a la 2001 vastness) and come to their most memorable mission, Mill operator's Planet. Amelia feels as though she has touched someone's hand as she passes through the wormhole.

They are located 10 billion light years away from Earth in a region of space. Because of the planet's close proximity to Gargantua, which results in a significant gravitational time dilation, they decide to head straight for Miller's planet, with the intention of making only a brief stop there. Each hour spent on its surface costs seven Earth years. Cooper, Doyle, and the robot CASE decide to put themselves in danger and plan to survey the area in a matter of minutes, while Romilly stays on the Endurance to investigate the black hole and extract quantum information from it. At the point when they land, all they find is shallow water and destruction of Mill operator's boat, who obviously passed on and had shown up only a little while prior, despite the fact that she sent the thumbs up signal on Earth 10 years prior. The crew believes they can see mountains in the distance, but what they actually see are enormous tsunami waves. Brand gets stuck under the Miller wreckage and has to be pulled back by CASE. Doyle drowns, the ship is flooded, and they won't be able to get out for an hour, which will cost them years. Cooper forgives Brand's error despite his frustration with her. Cooper starts the engines after the water has mostly drained them, but he only manages to get away from the next wave and land on the surface.

When Cooper and Brand return to the Endurance, they find an elderly, gray Romilly wearing a robe. After 23 Earth years, Romilly has spent most of her time waiting, with a few periods of cryosleep. On Earth, the year 2090 is around the corner. Brand is relieved to learn that her father is still alive and well, even though they are all beyond devastated. They can receive messages from Earth but cannot send them. Cooper looks over all of the videos and breaks down 23 years of recorded footage. He sees his 17-year-old son Tom showing a picture of the girl he thinks is right for him. In the following video, Tom (presently played by Casey Affleck) acquaints with Cooper to his grandson Jesse. In the following video, a now climate beaten and 40-year-old Tom uncovers that Donald kicked the bucket seven days prior and is covered close to Jesse and that he trusts Cooper to be absent or dead and necessities to let him go. Then, Murph, now played by Jessica Chastain, makes an apparent live recording. Following 25 years of quietness, a still difficult and disheartened Murph tells off her dad for not satisfying the chance of being back since she is presently 35 years old, which is a similar age he was the point at which he left Earth. He feels as though a knife has been stabbed into his heart, and he has no way of communicating with her back.

Murph stops recording the video on Earth. She is now confined to a wheelchair and works for Dr. Brand, living in the NASA bunker, and she is approximately 90 years old. Brand is as yet attempting to settle the deficient gravity condition to get Plan A rolling and is consoling Murph that the group of the Perseverance are accepting their recorded messages, yet the team can't communicate out.

Because they only have enough fuel to visit one of the planets before returning to Earth, the Endurance crew debate whether to visit Mann's planet or Edmond's planet now that they have recovered emotionally from Murph's video. Cooper wants to go to Mann's because he's still transmitting his beacon, but Brand wants to go to Edmond's Planet because it seems like his planet has a better chance of success.

Murph and her farmer brother Tom go back to the old Cooper homestead on Earth. Due to the spreading blight, he has just burned off a third of his crop. He presently has his old neighbor's yield to develop since the neighbor moved or passed on. They think that the farm won't produce anything soon. Together with Tom, his wife Lois (Leah Cairns), and son Coop, she eats corn soufflé and corn on the cob for dinner. She learns that Coop has a severe cough. She declines their request to stay the night due to negative childhood experiences. Murph is aware that their son is suffering more and more each day as a result of the air's nitrogen levels.

Murph returns to the NASA bunker a day or two later to learn that Dr. Brand has passed away. He admits to her that he had lied to her and that Plan A is impossible. He couldn't figure out how to get people off Earth by solving the gravity problem. She accepts her dad had a profound knowledge of Brand's plan and that he got away and intentionally left her and every other person to bite the dust. Died Dr. Brand. Murph sends a video message to Amelia illuminating her regarding her dad's demise and beseeches him to come clean that the entire situation had been a joke.

A few months later, the Endurance crew reaches Mann's Planet; The planet has ice clouds, a poisonous methane atmosphere, and glaciers that cover it year-round. Dr. Mann (Matt Damon), who has been in cryosleep for more than 35 years, is awoken by Cooper, suffers a mental breakdown, and is relieved that he has been saved. He describes the icy but beautiful world in which he lives, indicating that it possesses 80% of Earth's gravity and that some of it is habitable, possibly even containing a source of fresh water.

Brand sees the video Murph sent about Plan A being a ruse and her father's death. She is totally stunned and had no clue, yet Mann consoles her the condition was really tackled some time in the not entirely set in stone to be unthinkable before he at any point went on the mission. To ever obtain data, one would have to enter a black hole, which would necessitate death.

Back on Earth, Murph is driving her Jeep through the gloomy plains with her boyfriend, Dr. Getty (Topher Grace), another NASA physicist. They are observing the endless clouds of black smoke and families with their decrepit 80-90-year-old vehicles on the road with their belongings in tow, similar to Midwestern farmers fleeing to the west in the 1930s to find a better life. She is aware that Dr. Brand only provided a portion of the equation, and that it can be solved as long as it comes from a black hole. She has a gut feeling that the coordinates of the dust on the floor of her bedroom, along with the Morse code message telling Cooper to "stay" and the books being pushed off the shelf, gave her a clue long ago. She believes that this "ghost" is a being that has attempted to comfort her and aid in humanity's survival. She knows it's not the end and that humankind is using up all available time.

Mann is simultaneously showing Cooper the dangerous, icy world. Dr. Getty is checking the lungs of Tom's son while Murph is back at the Cooper homestead. Tom, Murph's brother, is appalled by Dr. Getty's statement that they can't stay and will die, and he punches him in the face as Dr. Mann removes Cooper's voice beacon and sends Cooper plunging off the cliff. Mann uncovers to Cooper that the planet is appalling and that he conveyed the message so he could take Cooper's spaceship to get back to Earth. Tom outright refuses and tells Murph to leave, believing it is his responsibility to care for the farm in order to fulfill his promise to his father. Murph confronts Tom and reveals that her father never intended to save them but rather to escape and leave it up to her. Cooper is being suffocated by the ammonia-rich air as a result of Mann's attempt to kill him by breaking the visor on his helmet.

Cooper is able to reach his voice beacon, which Mann removed from his helmet so that he could call Brand to come rescue him. Murph and Dr. Getty are returning to NASA when, in a fit of rage, she pulls over, pours gasoline over corn crops, and sets them ablaze in an effort to distract Tom and return to the farmhouse. Cooper has been protected by Brand. Romilly was killed when Mann's planet-based living quarters burst into flames. Romilly was killed while attempting to retrieve data from Mann's booby-trapped robot KIPP, which was supposed to reveal the planet's truth. Cooper and Brand rescue TARS from the rubble, and then they leave the planet.

On Earth, Tom's family has left the house, and Murph is trying to make sense of the past in her old bedroom. Mann is also attempting to leave the planet in a different shuttle and refuses to listen to Cooper and Brand's pleas not to dock with the Endurance. Murph is in her room looking at her old effects to figure out what the "phantom" may be telling her.

Dr. Mann continues to work despite the fact that Cooper and Brand have repeatedly warned him not to dock with the Endurance. He has manually moved the ship into position for docking, but he ignores the computer's warnings about "imperfect lock." As a result, the docking pincers attempt to grab, but they don't lock in. In mid-sentence the coupling discharge and the rough ejection of air into space conveys him with it, and coming about impact causes a blast. Cooper informs Brand that, despite the Endurance's rapid rotation, he will dock with it now that it is out of control. However the outward g-powers from the twist are tremendous, Cooper can dock. In any case, they can't return to Earth and need to go to Edmond's Planet to try and expect to get by, in light of the existence support being obliterated. They need to slingshot around the dark opening Gargantua to come to Edmond's Planet and on manual controls.

Cooper and TARS sacrifice themselves to collect data on the singularity and propel Amelia and CASE faster by reducing the ship's mass during the harrowing orbit around Gargantua by detaching their respective shuttles. Brand is on a path that will lead her to Edmond's Planet when Cooper leaves her in his Ranger without her knowing. He takes a chance despite the fact that he is aware that the cost of orbiting the black hole will be 51 Earth years due to the gravitational time dilation. Cooper has outraged the brand, who is now left alone with CASE.

Gravitational forces begin to break apart Cooper's shuttle as it enters the black hole. Pellets striking Cooper's Ranger spaceship resemble sleet as he descends toward the black hole's center. He does what the ship's computer tells him to do, ejecting himself without hesitation.

Cooper believes he is dead as he descends into the black hole and finds himself in a grid of cubbyholes, unaware of the tesseract-like surroundings in which he is trapped. Murph, ten, reacts to an object falling from her bookshelf back at the farmhouse after he hits it along with a bunch of others that look like books stacked and knocks it down. The lunar lander model that was shown at the beginning of the movie was destroyed by him. He yells out to Murph, but she takes it and doesn't hear him. Then he sees Murph pleading with her father not to leave in a different part of the grid. By removing the books from the shelf and using Morse Code, Cooper watches this and begs himself not to leave. When he realizes that he should have listened rather than going on the mission, Cooper breaks down. Then, while the fire is still burning, adult Murph appears in the bedroom, and she realizes that her father was the ghost who was reassuring and comforting her. She is no longer enraged with him and has hope now that everything makes sense to her. She remembers the dust storm coordinates and the books falling off, but she is still trying to figure out what her father is trying to tell her.

Cooper is liberated from his grief-stricken state of survival by TARS, who informs him that he was sent there by fifth-dimensional beings to communicate with Murph and to assist his daughter. Cooper is overjoyed to see that TARS is with him. Cooper is aware that the mission was not a mistake and that he will complete the tasks required of him. Cooper has been selected to assist in the engineering of humanity, whereas Murph has been selected to save humanity. He sends NASA the coordinates from the farmhouse to himself, and then, using Morse Code, he sends the gravity equation from the black hole to the wristwatch he gave Murph before he left through TARS. Cooper was able to add the equation for the black hole to the watch because preteen Murph had placed it back on the shelf. Adult Murph sees the second hand with the Morse Code and realizes that it is the key when she takes the old wristwatch out of a box of her old keepsakes. Because the fire is out, Dr. Getty is pleading with Murph to leave and for them to leave. Tom is enraged when Murph returns to the farmhouse with the watch, but she tells him about it, embraces him, and assures him that her father was the ghost all along and will save them. Tom accepts her hug despite his confusion about everything.

Using the information from the wristwatch, Murph completes the equation when he returns to the NASA bunker. She records everything and tosses the equation-solving papers off the deck of the centrifuge in construction. She kisses Dr. Getty in an attack of joy. Therefore, what will occur soon may save the majority of humanity.

The tesseract is now closing in on itself back in the black hole, and Cooper is convinced that everything worked. He is reassured that future humans built it to make this happen, and he tells TARS that everything is fine. When it passes through the wormhole, he sees the Endurance and touches Brand's hand. After that, he is knocked unconscious and thrown into Saturn's orbit with a couple of beaming lights coming toward him.

Cooper awakens to wind up in an emergency clinic bed. a very clean room with the sounds of birds chirping and a baseball bat cracking the ball in the background. He is jokingly informed by a doctor that he is now 124 years old, but he still appears to be in his mid- to late-30s. Cooper is told by the doctor that he is extremely fortunate to be alive because space rangers discovered him with only minutes left in his oxygen supply. Cooper looks outside the window of his room with kids playing baseball with a hitter hitting a ball up high, which ends up being the bay window of a topsy turvy house with kids cheering at the window being broken. Cooper believes that Cooper Station, which orbits Saturn, is named after him after he is informed that it is, in fact, named after his daughter Murph. Despite her age and health, she is still living on another space station and will be there in a few weeks to see him. Cooper is happy that Plan An accomplished for sure work out and that the gravity condition was tackled. The same centrifuge that served as the bunker for NASA is now a space station where humans can live.

A tour guide has now released Cooper from his hospital room and taken him to the station, an O'Neill cylinder that looks like an old-fashioned American rural setting and has artificial sunlight beaming from one side. This is the same location where the rocket took off 89 years ago. He takes great interest in a group of sleek ranger ships that are more effective than the ones he used as they pass by. He is directed to a gallery show, which is his old farmhouse, just much cleaner and reestablished. You can find videos all over the place of elderly people talking about the dust bowl they lived in, including his daughter, who you saw at the beginning of the movie. He immediately repairs a damaged TARS that he discovered in the rangers' recovered farmhouse.

That "night," Cooper and TARS are drinking beer on the front porch like he and Donald used to, but he is extremely dissatisfied with the fake surroundings and pretending to be at home. He still longs to discover the unknown and is more interested in the spaceships than anything else. Additionally, he was not welcomed back as a hero because almost everyone he knew has passed away.

Cooper is about to enter the hospital room where the elderly Murph, now played by Ellen Burstyn, is spending her final days. Murph had demanded that she be brought to the station to say goodbye to her father. Cooper hears from a nurse that her family is inside and that she has been in cryosleep for two years. He carefully opens the door to find more than a dozen people, ranging in age from young children to middle-aged adults, surrounding her bed, unaware that she had a family. While his grandchildren, great-grandchildren, and spouses are present, he does not pay them any attention despite the fact that they are perplexed by his appearance. Visiting his daughter is his primary interest. Even though he is the same age as when he left and she is 99 years old and on the verge of death, he takes her hand without hesitation or awkwardness, and Murph breaks down in delight at seeing him. He reassures her that, despite the fact that no one believed her, she had known for years that he was the ghost who spoke to her in her room. He tells her he's presently here for her, yet in her still fiery and difficult ways, she doesn't believe he should see her pass on, saying her children are hanging around for herself and that she excused him and buried the hatchet with his vanishing many years prior.

She is surrounded by her beloved family as well as his unknown descendants as Cooper slowly leaves her room for a final visit. He decides to follow Murph's advice and go in search of Amelia Brand, who has arrived on Edmond's Planet to begin colonizing it. He is aware that the space station is not where he belongs. It's the best humanity can do outside of space stations, though it is a desolate place that looks like Mars because the air is breathable and can support life. Amelia continues to set up camp and put herself into cryosleep, but Edmonds passed away a long time ago and was buried by CASE. Cooper steals a new ranger ship that he has been obsessing over and goes through the wormhole with TARS to find her and defeat the rangers in their mission.
