Antonio Guerrero, whose successes in the ring are countless, has the beautiful Carmen as his mistress, and she adores him. With almost brotherly solicitude, he trains a young apprentice, Manolo. At the end of a bullfight where, once again, he has aroused the public's enthusiasm, Antonio meets Linda, a beautiful, unscrupulous American nymphomaniac, with whom he soon falls in love, much to Carmen's despair.
