Cast & Crew
When Bruce McLean arrives in Mexico on a mining expedition, he meets Paula Figueroa, and they quickly fall in love. Because he also loves her, revolutionary outlaw Emiliano Pacheco kidnaps Bruce when he hears about the relationship. For a ransom, Emiliano demands one night with Paula, terms to which she agrees. As soon as Bruce has been released and is safely across the border, however, Paula kills herself rather than sleep with Emiliano. [In the alternate ending, Bruce rounds up some cowboys after his release, and then returns with his posse to Emiliano's camp, where they save Paula and kill Emiliano and his men.]
Two endings were filmed for The Heart of Paula, a happy one and a tragic one, and exhibitors were given the choice of which one to show. Scenes from the film were shot in Tijuana, Mexico. Wid's lists William Taylor as the film's director, but the film's titles contain the credit "Produced under the direction of Julia Crawford Ivers."

Del Rio as the prison attendant; "Pascal" as the Mexican who plays guitar; Joe Ray as the bandit who serves as a guide; "Preston" as a Mexican officer; "Dillon" as Pacheco's mistress; "Siliera" as the Mexican subaltern; Mrs. Rosa Robles as the duenna; "Mendez" as Dieguez; J. Segola, F. Ramerez, M. Gill, A. Renez, A. Boreno, "Rios," J. Marical, F. Callas, J. Adanta, P. Martinez, "Espinosa," "Valdez" and "Hill" as soldiers; and Earl Arms, Pete Loftus, Earl Garber and Charles Carter as cowboys.
