Decaying Orbit(2007)

When a mysterious explosion destroys a space station on the edge of the galaxy, five survivors manage to board an escape shuttle. Left adrift without communications, food or any means of leaving the system, the survivors are forced to work together to survive. But soon evidence surfaces that one of them may actually be the saboteur who caused the station's destruction. Can the dysfunctional group band together long enough to be rescued, when no one knows who they can trust?
