After the elevators at a New York City skyscraper begin inexplicably malfunctioning, putting its passengers at risk, mechanic Mark Newman and reporter Jennifer Evans begin separate investigations. Newman gets resistance from superiors at his company, which manufactured the elevator, while additional elevator incidents cause several gruesome deaths. The police get involved and suspect that terrorists are responsible, but a far stranger explanation looms.

The spaceship, Starship Avalon, in its 120-year voyage to a distant colony planet known as the "Homestead Colony" and transporting 5,258 people has a malfunction in one of its sleep chambers. As a result one hibernation pod opens prematurely and the one person that awakes, Jim Preston (Chris Pratt) is stranded on the spaceship, still 90 years from his destination.
