Both animal and human nostrils flare, and passion reigns in this classic romantic tragedy with Rudolph Valentino. Valentino is Juan Gallarde, an aspiring bullfighter, married to his loving childhood sweetheart Carmen (Lila Lee). But as his fame rises as a matador, so does his hot Spanish blood, and he succumbs to the passionate embraces of the sultry Doña Sol (Nita Naldi). When Juan is gored by a bull, his bullfighting fame is cut short, and Carmen returns to his side to nurse him back to health, and, as he struggles to regain his strength and make a comeback in the bullring, Carmen is there for him. At last he returns to the bullring, but in the stands, Juan sees Doña Sol with another lover. His attention distracted, a furious bull charges him and he is killed, dying in the arms of Carmen. ~ Paul Brenner, Rovi
