A pair of crew members aboard a spaceship wake up with no knowledge of their mission or their identities. This 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 spacecraft. They can't remember anything—who are they, what is their mission? The only way out of the chamber is a dark and narrow airshaft.
