Safe (2012)

Luke Wright is a two-bit cage fighter, until the day he throws a fixed match. 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, a young girl whose memory holds a priceless numerical code, being pursued by the same gangsters who killed his wife, Luke impulsively jumps to action.
