Six crew members on a derelict spaceship awaken from stasis and have no memory of who they are or how they got on the vessel.

While still struggling with revelations about their pasts, the crew must make a terrible decision: assist miners facing insurmountable odds or abandoning them to certain death.

The ship mysteriously veers off course, and the crew suspect sabotage. Repairs require a perilous spacewalk and Five makes a shocking discovery.

When the ship stops at a space station, some of the crew encounter haunting details of their mysterious pasts.

Mounting a salvage operation on an apparently deserted space freighter, the crew find deadly cargo.

Attempting to uncover Five's buried memories, the crew turn to chemical hypnosis and the ship's neural link.
