Two astronauts (Dennis Quaid and Ben Foster) awaken in a hyper-sleep chamber aboard a seemingly abandoned spacecraft. Its pitch black, they are disoriented, and the only sound is a low rumble and creak from the belly of the ship. They cant remember anything like who they are and what their mission is, but one thing they do realise very quickly is that that they are not alone. Slowly the spacecrafts shocking, deadly secrets are revealed and the astronauts find that they must fight to stay alive and that their survival is more important than they could ever have imagined
