A student, an ex-con, an engineer, a social worker, a cop and a mentally handicapped person are caught like rats in a trap in a maze of interlocking cubes with no apparent way out. They're clueless as to how they got there or why they were chosen. Food or water is nowhere to be found, and upon further investigation, the six discover some of the rooms are booby-trapped with destructive devices.
