Sam Lash (Gary Cooper) is a fur trapper with a randy reputation when it comes to women. But when Sam meets tempestuous Mexican damsel Lola Salazar (Velez), he falls deeply in love for the first time in his life. Lola's aristocratic father Don Solomon (Michael Vavitch) disapproves of the romance, forcing Sam to kidnap the girl and high-tail it to the mountains. After a brief period of marital contentment, Sam gets restless and leaves Lola, preferring the company of his trapper pals Gullion (Louis Wolheim) and Rube (Constantin Romanoff). But he relents and returns to his bride—making short work of his bitter enemy, Indian leader Black Wolf (George Rigas).
