In Adventure in Fishing Harbour Yee Tat found an engrossing mix of chivalry, action and melodrama, with scenic locations of Taiwan and the magnetic performance of Kenneth Tsang to boot, a film the original writer described as his best at the time. In his first villainous role, Tsang inhabited an all-evil character, Kam-fu, gangster Lee Da-lung (Kong Man-sing)’s adoptive brother. With Tailung serving time behind bars in his stead, Kam-fu forces himself on their adoptive sister Yuen-ting (Connie Chan Po-chu), Tai-lung’s lover who joins the police and uncovers the brothers’ illegal dealings in the fish market in an undercover operation. Upon Tai-lung’s release, a feud begins between the brothers and complicated by the rivalry over the woman. Kam-fu’s attempt to oust his brother from power by bribing the police to launch a raid resolves itself into a deadly duel between the brothers and the gangsters’ assets bequeathed to good causes.
