Two astronauts awaken in a hyper-sleep chamber aboard a seemingly abandoned spacecraft. It's pitch black, they are disoriented, and the only sound is a low rumble and creak from the belly of the ship. They can't remember anything: Who are they? What is their mission?
With Lt. Payton (Quaid) staying behind to guide him via radio transmitter, Cpl. Bower (Foster) ventures deep into the ship and begins to uncover a terrifying reality. Slowly the spacecraft's shocking, deadly secrets are revealed... and the astronauts find their own survival is more important than they could ever have imagined.
