 Don Diego de la Vega shows his trusted houseboy Felipe how astronomy studies the moon, and dreams about mankind going there one day, when his telescope sees a horseman approaching the pueblo hastily. It s a certain señor Morales, who most unkindly asks a room in her inn and commandeers señorita Victoria Escalante to wake him at dawn; when she does, she is found standing over his body, with a bloody stab-wound, arrested and quickly condemned to death by Alcalde Luis Ramone. Diego investigates, and discovers the alcalde actually used his friend, Mexico City s actor Ricardo Cortez, to play dead in order to set a trap for Zorro, but the fox is hard to bait and even harder to catch in a trap...
