Mark Kerr is one of the great champions of a violent and dangerous sport -- "no holds barred fighting" or "mixed martial arts fighting," in which challengers of any fighting sport (boxing, wrestling, kickboxing, karate, and so on) may challenge one another, without observing the official rules of either sport. In "no holds barred" fighting, the two competitors attempt to reduce one another to a bloody pulp, and Kerr is one of the best men in the game. But behind his violent exterior is an intelligent man who has made a decision to pursue a career in a wildly dangerous profession. MPAA Rating: R for violence, some language and drug content. Cast: Mark Kerr, Mark Coleman and dawn Staples
