Cube³

My idea for the 4th Cube instalment.

8 Prisoner's guilty of severe crimes, are placed in the Cube with no recollection, one of which is actually innocent, a man guilty of murdering his wife, but still confused about the whole thing, until his memory gradually returns while in the Cube. It turns out the innocent man was one of the engineers who created the Cube and was framed and set up to find faults/glitches in the Cube, which he does, but the men stranded inside with him, think he's apart of something more sinister.
