What happens
Clark Kent and Jimmy Olsen are trying to reach the leaders behind a campaign of hatred and intolerance in Metropolis. Jimmy goes undercover as a tough young hoodlum and gets himself admitted to the pool room hangout of Muggs and his gang. There he learns that the gang has recently been involved in trouble, and he arranges to return the next night. Afterward Jimmy phones Clark Kent from a drugstore to report what he has learned. A boy named Dutch, who was apparently listening nearby, then leaves the store and heads back to the pool room, so Jimmy and Clark face the risk that their plan has been exposed. This is the Adventures of Superman series, first broadcast on April 25, 1946.

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.
