Olivia's kidnapping by corrupt deputy Otis Huckabee turns out to be a smoke screen for Otis' real intent, to begin running illegal whiskey and tequila from Mexico with the aid of bandit leader Juan Pedro Lopez. While Tucker and his good friend James Hamilton ride to track down the men who took his wife, Sheriff Eubanks seeks to arrest Tucker for the murder of two of his deputies. Meanwhile, a long running feud between opium dealer Queen Lu and brothel madam Mrs. Murphy comes to the surface, while Frisco Kate, a prostitute with eyes on Mrs. Murphy's empire, plays one side against the other, with the kidnapped Olivia as her pawn. Queen Lu has an ace up her sleeve as well. She knows Mrs. Murphy's true identity, and that information could land the madam in prison for the rest of her life.
