Gil Jones (Ronald Reagan) is an American who runs a Mexico ranch, which may have oil under it. A woman he loves, Lucia Pell (Laraine Day), has married a New York businessman, Morgan Pell (Tom Conway), possibly for his money. Jones and his Uncle Henry (Lionel Barrymore) are in debt and banker Jasper Hardy could foreclose at any time. Mexican bandit Pancho Lopez (Beery), meanwhile, rustles their cattle.
