Danny, a respected cop, is setup after an investigation goes wrong. While laying low in his new jail cell, Danny is forced to get involved in the inmates underground cage fighting circuit. With the help of Irving, a former mixed martial arts champion, Danny devises a scheme to bring justice and innocence to his family's name, if he can get out of the cage alive.

Errors made by characters (possibly deliberate errors by the filmmakers): During Danny's training, Irving says "There is a concept called Wushu, translated from the Japanese: no mind". Wushu is in fact not Japanese, it is Chinese and it simply means 'Martial Arts'.
