Rancher Clay (Robert Sterling) and his brother, Steve (Claude Jarman Jr.), head out across the Sonora mountain pass, followed by Lednov (John Ireland), an ex-con seeking revenge on Clay for putting him behind bars. Clay and Steve unexpectedly cross paths with a group of dance hall girls -- including Mary (Gloria Grahame), Marcia (Martha Hyer) and Helen (Myrna Dell) -- whose stagecoach has broken down, and help them get to the nearest ranch, where Lednov unfortunately catches up to Clay.
