Adrien Brody and Forest Whitaker star in this mind-shattering psychological thriller from the creator of TV's "Prison Break." Selected to participate in a two-week research project, a group of men agree to play inmates and guards in a simulation of life within a state prison. But as the 24 volunteers slip deeper into their roles, power corrupts, fears escalate and the experiment spins horribly out of control. Cam Gigandet, Clifton Collins Jr. and Maggie Grace co-star in this intensely shocking film.
