Sent into a drunken tailspin when his entire unit is killed by a gang of thrill-seeking punks, disgraced Hong Kong police inspector Wing needs help from his new rookie partner, with a troubled past of his own, to climb out of the bottle and track down the gang and its ruthless leader.
In this prequel to the original, a bloody power struggle among the Triads coincides with the 1997 handover of Hong Kong, setting up the events of the first film.
