Reporter Clark Kent of the Daily Planet, whose secret identity is that of Superman, sees with his super vision, the Spirit being choked to death by the Frankenstein Monster. Quickly changing into Superman, he flies to the Spirit's aid, and battles the powerful monster. Superman grabs the monster and flies into the sky. Unfortunately for the monster, it slips out of its jacket and plummets to its death. Superman and the Spirit proceed to the lair of the Phantom Avenger. Before he can be of any more help, Superman is zapped with a Kryptonite ray. Alone, the Spirit battles the Phantom Avenger, knocking the Phantom onto a ray gun that kills him. The Spirit unmasked the Phantom Avenger, revealing the distorted face of the Phantom of the Opera. The Spirit now uses the ray gun to destroy the Kryptonite. Now free, Superman bids adieu and flies away. The Spirit walks of into the distance, while another hero, Rocket Man descends from the sky.
