Captain from Castile

In the spring of 1518, near Jaén, Spain, Pedro de Vargas (Tyrone Power), a Castile (historical region) Knight, helps a runaway Aztec slave, Coatl (Jay Silverheels), escape his cruel master, Diego de Silva (John Sutton (actor)). De Silva is ''el supremo'' of the ''Hermandad'', charged with enforcing the Inquisition, and Pedro's rival for the affections of the beautiful Lady Luisa de Carvajal (Barbara Jo Lawrence). Later, Pedro rescues barmaid Catana Pérez (Jean Peters) from de Silva's men. At the inn where Catana works, Pedro becomes acquainted with Juan García (Lee J. Cobb), an adventurer just returned from the New World to see his mother.
