In the steamy, claustrophobic confines of Rio's toughest prison, carnal desires run amok. Muscled, hung convicts, locked away from the world, find their Release in each other's arms.

The air is thick with the scent of sweat, sex, and the forbidden, as they leave their inhibitions behind the locked cell doors.
