He who makes a mistake dies: this is the law of the Daughter of the Dragon. Wong experiences it first hand along with his bootlickers: he is strangled while they are devoured alive by rats! In the meantime, while the pards massage dozens of oafs with the help of Lefty Potrero’s body-builders, Tex gets an offer of help from Lim You , son of the defunct Wong, who is racked by thoughts of getting his revenge on Ah-Toy. And in the hall of Mike Tracy’s Hotel Alameda, our heroes discuss a plan of attack: their idea is to disguise themselves as vigilantes and destroy all the opium dens of the Tong, starting with Yreka’s, run by Yat Sing.
