An ex-cop in search of redemption agrees to pose as an inmate at one of the most brutal prisons in the country in order to investigate a series of suspicious murders at the notorious penitentiary. Burke Wyatt (Johnny Messner) has lost everything. A once-respected cop whose life has fallen to ruin, Burke realizes that he's got one last chance to prove his worth. The inmates at Cainesville State Prison are dropping like flies, and no one on the force can get any answers. Their only hope for cracking the case is for Burke to pose as a convict and conduct his investigation from the inside. Once inside, Burke discovers that the inmates are being forced to fight to the death as part of an underground fighting ring. When Burke becomes the latest fighter to venture into "the cage," he must pummel his opponent into oblivion if he hopes to crack the case and live to see another day.
