Tempers flare and fists fly in this action-packed sagebrush classic based on the real-life adventures of a young tenderfoot turned tough cattleman. Glenn Ford stars as Tom Reece, a range-hardened trail boss who has just arrived in Chicago after months on the plains. When he loses all his money in a high-stakes poker game, he reluctantly accepts a $3,800 loan from hotel desk clerk Frank Harris (Jack Lemmon) in exchange for a piece of his cattle business. Frank, a would-be cowboy, has fallen hopelessly in love with Maria Vidal (Anna Kashfi), the daughter of a wealthy Mexican rancher. Though her father forbids the lovers from seeing each other, Frank holds Tom to their partnership agreement, and forces the feisty wrangler to take him on the cattle drive to Maria's hometown of Guadalupe. There, the two men find all the excitement they can handle in this all-star Technicolor tale of fiery emotions and dangerous desires.
