The Louisiana wedding of debutante Phoebe Ann Naylor to Don Andrea de Baldasar, El Duce de la Casala is stopped by the Cavalry over a matter of honor. Don Andrea flees across the river to Texas, where he meets up with Sam Hollis and his Indian sidekick, Kronk, who are carrying rifles to the town of Moccasin Flats. Don Andrea rescues an Indian maiden, Lonetta, tames some longhorns, competes with Sam for Phoebe's affections, eludes a Comanche war party and the cavalry and ultimately saves the town and gets his girl.
