Isaiah Bone (Michael Jai White) is an ex-con with an amazing ability to use mixed martial arts to his advantage. Bone wants to become an underground icon in the illegal business of street fighting, but he must deal first with a dangerous manager named James (Eamonn Walker). Higher up in the mob is Franklin McVeigh (Julian Sands) who is the true power behind the illegal fight clubs. With his friend Pinball (Dante Basco), Bone expects to pound the opposition one man at a time. But, Bone may have an ulterior motive for his climb into the cage of crime. He is not happy about heroin addicts like Angela (Michelle Belegrin) who are the real victims of crime czar McVeigh.
