The Mark of Zorro

Don Diego Vega (Power) is summoned home from his elite training corps in Spain to California, where he finds his father deposed and the people living in tyranny. Disguised as Zorro, a sword-wielding mystery man dressed in black, he works to restore his father to power and return the tax money stolen by the villains (J. Edward Bromberg, Basil Rathbone). He even finds time to romance the ruling tyrant's beautiful niece (Linda Darnell). (official distributor synopsis)
