Jim (Chris Pratt) is a working-class passenger on the Avalon spacecraft. During the 120-year journey to the space colony Home 2, he woke up from cryosleep due to an accident. Finding that he might have to spend 89 years alone on this huge ship, Jim tried to fall asleep again, but in the end he could only live alone in a sleeping cabin with 5,000 fellow passengers. Jim, who was on the verge of suicide, was desperate and desperate, so he woke up a female passenger Aurora (Jennifer Lawrence), and the two had a spark of love during their time together. When the operating system of the spacecraft was paralyzed, the couple faced bigger problems. Their lives were threatened not only by themselves, but also by their fellow travelers and the voyage itself.
