There's something very calculated about this Rudolph Valentino vehicle. As he did in Four Horsemen of the Apocalypse, the star plays an Argentine with a talent for the tango. The production and costuming are elaborate, and the story was based on the Rex Beach novel Rope's End. But none of this can help a weak plot line which is stretched mighty thin to last for nine reels. It is arranged for Don Alonzo de Castro to marry Julietta (Helen D'Algy), who comes from a noble Spanish family. Castro's jealous ex-girlfriend, Carlotta (Nita Naldi), schemes with bandit El Tigre (George Siegmann) to destroy their happiness. On the couple's wedding night, El Tigre stages a raid and kidnaps Julietta. Carlos goes after him, but is enraged when he sees a woman with a bridal veil embracing the bandit. He believes it is Julietta, when it's actually Carlotta. Castro plans revenge on El Tigre. Meanwhile, Julietta escapes to a nunnery with the help of Carmelita, a dancing girl (Louise Lagrange). Although Carmelita loves Castro herself, she eventually reveals Julietta's hiding place and the couple are reunited.
