Cube Zero is a 2004 Canadian science fiction psychological horror film written and directed by Ernie Barbarash, in his directorial debut.

It reverts to the industrial-designed, colored rooms of the first Cube, but with a refreshed and redesigned set.

The pair play chess during work, whereupon Wynn demonstrates abilities which he uses to predict moves.

A call from their superiors instructs Wynn and Dodd to perform a procedure for Owen who has reached one of the exits of the Cube.

This shuts down every trap and initiates a mode, which gives the prisoners ten minutes to escape the Cube as its rooms return to their positions, before a procedure vaporizes everything inside.

Jax discovers Dodd's betrayal and kills him, then he activates Haskell's agent through a chip implanted in him.

He wakes up in a room, where Jax informs him that he has been sentenced for treason, and that he had agreed to become a subject, despite Wynn remembering neither the trial nor signing the consent.

Wynn's brain is altered, and he dreams about Rains reuniting with her daughter and praising him as a superhero.
