Zorro (1957)

Diego de la Vega, heir to a prosperous estate, returns from his education in Spain only to find Los Angeles oppressed by the tyrannical Capitan Monastario. Disturbed by the rampant abuse of power, Diego realizes he can't confront Monastario directly. Instead, he cleverly assumes the alter ego of Zorro, a masked avenger cloaked in black. With wit and skill, he takes to the shadows, determined to challenge Monastario's regime and restore justice to his beleaguered community.
