The spaceship, Starship Avalon, in its 120-year voyage to a distant colony planet known as the "Homestead Colony" and transporting 5,259 people has a malfunction in two of its sleep chambers. As a result two hibernation pods open prematurely and the two people that awoke, Jim Preston (Chris Pratt) and Aurora Dunn (Jennifer Lawrence), are stranded on the spaceship, still 90 years from their destination.
