Chow Yun-Fat (Hard Boiled, A Better Tomorrow) stars in this sizzling, highly influential crime drama from director Ringo Lam (Full Contact, Prison On Fire, Maximum Risk). Ko Chow is an undercover cop torn between his duty as a police officer and his loyalty to his friends on the wrong side of the law. He wants out – and his commanding officer Inspector Lau reluctantly approves his resignation – but only after he completes one final assignment. Tasked with infiltrating a notorious gang of criminals, Chow bonds with their leader (Danny Lee, The Killer), building a relationship based on mutual trust and respect. But when a planned heist turns into a violent shootout with the law, the tension among the thieves heats up ... and they begin to suspect there is an informant in their midst.
