When Jeff's (Hong Kong superstar Chow Yun-Fat in true hard-case form) friend Sam (Anthony Wong) steps on the feet of a local loan shark, Jeff comes to his rescue, creating a powerful enemy in the vengeful gangster. Seeking to skip town and make good, the two hatch a plan to hijack an arms shipment with the help of Sam's flamboyant and malicious cousin Judge (a delightfully sleazy Simon Yam) and his gang of dysfunctional thugs. What Jeff doesn't know is that he's being double-crossed by the wild group of brutal killers, who plan to bury him as they make their getaway. Judge forces Sam to off his loyal friend Jeff, but Sam botches the job, leaving Jeff to return for bitter revenge after dealing with an emotionally painful betrayal and a physically challenging rehabilitation.
