A Chinese boy escapes from a ship in San Pedro's harbor and tries to hide in Los Angeles. He is unable to seek help, for he speaks only his native language. Discovered hiding in Tomas Gregorio's warehouse, he is arrested as a thief. The boy's only hope is a scribbled message he gives to Diego. Not knowing Chinese, Diego sends it to the mission, knowing Father Ignacio can translate it. The reply has not yet arrived when a sailor claims that the boy is an escaped murderer being transported back to stand trial. Vinson, the sailor, convinces Garcia to hand over custody of the prisoner, and he begins the trip back to San Pedro. Father Ignacio then tells Diego that the message says the boy is actually a member of Chinese royalty and is being held for ransom by Vinson. Zorro rides after the seaman and the unfortunate boy, surprising them on a narrow cliffside trail. Vinson and Zorro fight hand-to-hand, and Zorro has to throw the kidnapper off the cliff to save his own life. The boy is taken to a ship that will carry him safely home to China.
