K-11 (2012)

Dissolute record producer Ray Saxx finds himself thrown in jail on charges of murdering one of his top artists, an act he doesn't remember due to his characteristic drug haze. In prison, Ray is kept out of the general population and put in the K-11 unit, a pit of chronic sexual and drug abuse run by the depraved Sergeant Johnson, whose reign of terror comes to an end thanks to Ray's resourcefulness-- which might just lead to Ray's own redemption. (Kristen Stewart mentioned for the role of Birdy/Butterfly.)
