What happens
Clark Kent and Lois Lane, reporters at the Daily Planet, deal with the aftermath of poisoned candy sent in Kent's name by Nita, the Leopard Woman, leader of an oriental spy ring called the Society of the Leopard. Young Jimmy Olsen ate the candy and is near death. Kent, acting as Superman, flies to bring back Dr. Richards, a physician who knows about the poison, from a passenger ship at sea. After Jimmy is saved, Kent and Lois plan to make the spy ring believe the poison worked. Meanwhile Nita and her associate Max Heller plan to destroy an airplane they have found. Kent decides to visit a factory where Heller's gang was rounded up. This episode is part three of the serial, which was broadcast in 1942.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
