Lou Prophet loves to keep beautiful women company. But when the invitation comes from Miss Louisa Bonaventure, the Vengeance Queen, he finds himself intimate with hot lead instead of her warm female form. Louisa's got him riding the brutal Mexican frontier chasing outlaws led by Tony Lazzaro, a notorious thief whose deadly weapon, Sugar Delphi, is a blind and blood-hungry pistolera. While he and Louisa hunt for Lazzaro with two gangs hot on their tail, Lou prays that the pursuit ends with him on the right end of a smoking pistol.
