In the high-security confines of a state-of-the-art penitentiary, a routine prisoner transfer descends into a nightmarish fight for survival. Directed by David Gordon Green, "Supermax" plunges viewers into a claustrophobic world where the most dangerous criminals are not the only threat. When a catastrophic systems failure unleashes a wave of unspeakable horror within the prison's automated walls, a dedicated corrections officer finds himself trapped alongside the very inmates he was meant to guard. Forced into an uneasy alliance with a formidable convict, they must navigate a labyrinth of terror, where high-tech security measures turn against them and a sinister, inhuman presence begins hunting them all. Blending relentless action with palpable dread, this film crafts a tense atmosphere where every shadow in the sterile corridor could be hiding a new nightmare, and the ultimate prison break becomes a desperate race against a monstrous evil.
