Bart Maverick wins big, when he wins the ""Lucky Lady"" saloon in a card game. When Bart goes to Santa Leora to stake his claim, a beautiful Marquesa refuses to relinquish the property to him. Maverick encounters hurling knives, flurry of bullets and pounding fists when he tries to hold onto his newly acquired saloon.

Beau Maverick wins half-ownership in the Blue Bell Saloon in Arizona. In an attempt to raise funds for the floundering business, Beau and his partner Charlotte become partners with a mysterious gold prospector known only as the Dutchman. Along the trail to Superstition Mountain where the gold is located, Beau, Charlotte, and the Dutchman encounter danger in various forms.

Bart matches wits — and bullets — with a professional gunman... and learns that a beautiful woman can be more deadly than hired killers.
