In the movie "Passengers," Chris Pratt's character, Jim Preston, wakes up prematurely from hibernation aboard a spacecraft called the Avalon. The Avalon is on a 120-year journey to a distant planet, and all passengers are supposed to remain in hibernation until they reach their destination. However, a malfunction in Jim's hibernation pod causes him to wake up 90 years too early.

The reason behind Jim's awakening is a technical failure in his hibernation pod. The exact cause of the malfunction is not explicitly explained in the movie, but it is implied to be a rare and unfortunate occurrence. The malfunction disrupts the ship's automated systems, leading to Jim's awakening.

As the only awake passenger on the ship, Jim faces isolation and loneliness. Eventually, he makes the morally questionable decision to wake up another passenger, played by Jennifer Lawrence, in order to alleviate his loneliness. The story then unfolds as they navigate the challenges of being alone on the spacecraft and facing an uncertain future together.

It's important to note that the plot of "Passengers" has been a subject of discussion and controversy due to the ethical implications of Jim's actions. Some viewers have criticized the film for romanticizing Jim's decision to wake up another passenger without her consent, raising questions about consent, autonomy, and morality.
