Plot : Spoiler alert :- Seven-year-old Wen is vacationing with her parents, Eric and Andrew, at their remote cabin in rural Pennsylvania. While staying there, Wen is approached by a mysterious stranger named Leonard. Initially, he seems charming and explains that he needs Wen and her parents’ help to save the world. However, while Wen and Leonard spend time together catching grasshoppers, she becomes suspicious when three other people show up with makeshift weapons. Wen flees to warn Eric and Andrew, but the visitors break into the cabin, tie them up, and Eric sustains a concussion.
Insisting that they had never met before and that they have no desire to hurt the family, Leonard and his companions, Sabrina, Adriane, and Redmond, claim to have never met before this day. To find the family, however, they have been driven in recent days by visions and an unidentified power. The group predicts an oncoming apocalypse, according to Leonard, in which the oceans would rise, a pandemic will spread, the sky will fall, and eventually the earth will be enveloped in an unending darkness. The family must make a sacrifice of one of its members in order to stop this. They are informed that although though they will survive the end of the world, if they don’t make a decision, they will be the last people left alive. Eric and Andrew believe the organisation is lying and that the attack is being carried out for hatred and delusion.
When the family is unconvinced, the guests beat Redmond to death with their weapons while covering his head with a cloth as a sacrifice. Seriously injured Eric witnesses Redmond’s passing while observing a bright figure. Leonard claims that the beginning of the apocalypse has begun as a result of media reporting on deadly mega tsunamis. Redmond, whom Andrew suspects to be the homophobic attacker Rory O’Bannon who assaulted him in a bar years earlier and resulted in Andrew’s imprisonment, comes to Andrew’s attention. Rory may have sought him out in retaliation, according to Andrew. Leonard, Sabrina, and Adriane struggle with their guilt and Andrew’s assumption, yet they continue to believe in their visions. They reveal that Redmond’s death has unleashed the first disaster. The following day, the intruders sacrifice Adriane as the family remains indecisive once again. The disasters continue, as a deadly flu virus, which is particularly dangerous for children, spreads across the world.
Andrew believes that the events are unrelated and that the guests were expecting a scheduled newscast. Sabrina explains how her visions lead her and the other guests to connect online. After escaping, Andrew finds his car’s gun and begins shooting at Sabrina until she runs away. He proves to Leonard that he was Rory by locating Redmond’s wallet. Andrew thinks the four came in a truck nearby and proposes they use it to flee because they are hurt from his attack and have their tyres slashed. Andrew shoots Sabrina dead after she breaks into the house after Eric and Andrew lock Leonard in the restroom.
The programme shows spontaneous plane crashes happening all around the world as Leonard sacrifices Sabrina. As the sky grows dark, Leonard signals to the three that their time is almost up. He warns them that they will only have a short time to decide before it is too late once he dies. Leonard makes a self-sacrifice by slitting his own throat. After he passes away, the sky grows even darker, and lightning hits, setting out more fires and bringing down more aeroplanes. The Four Horsemen of the Apocalypse are represented by the intruders, Eric now believes that the happenings are true.Eric offers himself as the sacrifice because he doesn’t want Wen to grow up in a world that has been devastated. He admits that he witnessed a vision of Andrew and an adult Wen during Redmond’s sacrifice in the light. Eric believes that their family was picked because of their unconditional love to make the sacrifice. Andrew reluctantly shoots Eric to death before lightning strikes and burns the cabin.
