Clint Belmet (Gary Cooper) is supposed to hitch up with a wagon train and head out west. But, to make the journey, he must first evade a criminal charge by convincing a brassy French girl, Felice (Lily Damita), to pretend to be his wife. Now serving as a trail guide, Clint journeys with Felice across the frontier, where a real romance starts to develop between them. But Clint will have to keep his wits about him when the settlers are attacked by outlaw Lee Murdock (Fred Kohler).
