Before I get into it, let me caution that this film is gory, violent and jump-out-of-your-seat scary.
Earth is running out of resources and decided to send a massive space ship to an earth-like planet called Tanis.
After taking off, the crew members receive word that earth was destroyed; we're not told how.
Corporal Bower (Foster) awakens from deep hibernation, finds himself in a small room with no exit, then wakes his commanding officer, Payton (Quaid). Together they decide to find answers.
They can't remember much of their past, except what their tasks are on-board the ship.
Bower crawls through some air vents to get further into the ship, Payton directs him from a command chair.
This movie works on one level: you don't know more than the characters. As they learn things, about the ship and their pasts, you learn as well. It keeps you guessing until the end.
As Bower makes his way through the innards of the ship, he comes across other people who have been awake longer but are quite "wild". They are being hunted by these demon-looking creatures that carry sticks with glowing blue lights. (So you know when they're coming) And their screaming is ear-piercing. These blue-light bad guys like to eat you.
Where did they come from and how will Bower, Payton and the other humans escape?
The scares are intense but the editing is horrific. To make it "scarier" they blast you with loud high pitched noises with quick cut shots of the creatures running and screaming.
And the gory scenes are really over the top.
