In 1870, a shipment of $100,000 being transported by stagecoach to Galveston, Texas, is the object of a tug-of-war in the desert between Zack Thomas and Joe Jarrett, who first must stave off an outlaw band led by Matson.
Later, in Galveston, Thomas and Jarrett become rivals in a bid to open a waterfront casino. Each has a new romantic attachment as well, with the beauties Elya and Maxine, respectively. They eventually must join forces to hold off the villainous Matson and a corrupt banker, Burden, to keep their new gambling boat afloat.
