The plot it involves getting rid of the Devil Clan, a gang of very efficient robbers who have never been caught. The depredations must have gotten more blatant because two constables, played by Pearl Cheung Ling and Tin Hok are both tasked with eliminating them. Pearl Cheung recruits Lam Gwong-Wing who is either the third constable of the title or an informant. Lam is a bit of a goofâ??he would rather lounge in luxury with beautiful young women peeling grapes for him than go after the Devil Clanâ??which seems to make a lot of senseâ??but he reluctantly goes along with her after she threatens him. Lam is literally grabbed away from her by the constable played by Tin Hok for his war for his parallel operation. There is a third figure, neither a constable nor a Devil Clanner. He is Wolf Warrior who simply shows up and kills peopleâ??lots of people.
