One Nite In Mongkok

Mongkok, one of the most densely populated areas in the world, is the hotbed of illicit business. Lai (DANIEL WU), a farm boy from Mainland China, is hired as a killer and forced to enter into the gang warfare in Mongkok. He by chance saves a call girl, Dan (CECILIA CHEUNG), from the gangsters. The arrival of Lai tenses the police and the triad. Under flashy neon lights, who will find them first?
