A second-rate cage fighter on the mixed martial arts circuit, Luke Wright lives a numbing life of routine beatings and chump change...until the day he blows a rigged fight. Wanting to make an example of him, the Russian Mafia murders his family and banishes him from his life forever. But when he witnesses a frightened twelve-year-old Chinese girl, Mei, being pursued by the same gangsters who killed his wife, Luke impulsively jumps to action...and straight into the heart of a deadly high-stakes war. Realizing he's the only person Mei can trust, Luke tears a swath through the city's brutal underworld to save an innocent girl's life...and perhaps even redeem his own.
