A group of people, looking to earn a quick buck, sign up for a behavior experiment. But that may have been a really, really bad idea. The experiment causes even the pacifists to turn violent, and there is no one to stop them.
While its extremely fast paced, It has an interesting and intriguing storyline with great actors and some twists which, all in all, made me confused, excited, worried and even gave me an intense hatred for some of the characters.
Starring: Adrien Brody, Forest Whitaker, Cam Gigandet, Maggie Grace.
