Synopsis:
A new boy named John Smith comes to school. He wears a lead lined mask that prevents anyone from seeing his face. John quickly proves to be a star scholar, athlete, violinist, and actor. Superboy is unable to see John's face. When he notices that John's fingers have no callouses, the Boy of Steel realizes that he is being deceived.

An agent approaches, John's guardian Mr. Hench to offer the boy a movie contract. Superboy stops him from signing and proves that John Smith is really four different boys. Hench perpetrated the hoax to receive the wealthy contract. Hench is apprehended for fraud. The mystery boys who were pawns in the con man's scheme are then offered a chance to star in their own movie adventure.
