Zorro S01E04 - Double Entendre

The alcalde has the Indian camp ransacked, leaving Zorro's mark, so as to turn the whole pueblo against the 'bandit', finds copper ore on Indian land and has a fake Zorro, a master-swordsman, rob the church's poor box, which convinces most of the villagers. The real one rides to investigate, finds the alcalde's geology report and overhears him plan a fake duel with the impostor. The alcalde confiscates the Indian land but both 'duelists' are defeated by the real Zorro.
