Cube 2: Hypercube

After everyone but Kate (Kari Matchett) and Sasha (Grace Lynn Kung) is killed, Sasha reveals that she is the cyborg super hacker that everyone keeps talking about. Then everything seen in the various rooms starts appearing in one place, including a reincarnated Simon (Geraint Wyn Davies), who kills Sasha and is killed by Kate. Then Kate realizes that the number that has been in almost all the rooms is the time when the cube will implode. She takes Sasha's pendant (which apparently holds the secret to controlling hyperspace). Using it, she makes the only door left be the cube's exit, and finds herself confronted by the US military. She gives them the pendant, then is killed, apparently for knowing too much. Then the leader of the soldiers has a phone conversation which indicates that a third cube is being built.
