An extremely brutal armed robbery case has brought two very unusual young detectives together in Hong Kong. Both men have been known not to follow the usual rules of conduct in solving crimes. Lincoln, the younger brother of the deceased, an ex-policeman in China, has sworn to find the man who has murdered his brother. While he investigates the murder on his own in Hong Kong, he meets Michael, a CID officer on suspension. Michael has often been warned against insubordination and for pulling his own stunts to capture criminals on the run.
