Poor young street boxer Pang (Edison Chen) is smuggled into Hong Kong from Cambodia and forced to serve as an assassin. With the police soon on his trail, Pang hides at a dump and meets Yue, whose affections keep him from succumbing to his inner demons. Fanning the flames is the equally unstable Wai, one of the cops assigned to Pang's case. Relentless action and highly stylized violence permeate this fast-paced Hong Kong crime film.
