Oscar® winner William Holden stars as Peter Muncie, a drifter who, while en route to California, happens upon Tuscon's first female citizen, Phoebe Titus (Jean Arthur). Falling in love, Phoebe willingly abandons her tough, swaggering ways, giving up her pants for petticoats in an effort to get Peter to stay. Refusing to trade his wanderlust for home and hearth, Peter moves on, leaving Phoebe to throw herself into establishing a new freight line. But when a pair of villains (played by Warren William and Porter Hall) set out to muscle in on the new business, it's left up to Peter to return and help save the day for Phoebe.
