What happens
Clark Kent and Jimmy Olsen pressure Inspector Henderson for more time to expose the hate-mongering Guardians of America, a subversive group threatening a committee building a multi-faith children's gymnasium called Unity House. The reporters explain their plan: a staged news story about slashed paintings is meant to draw the group's leader out. Jimmy goes to the Guardians' headquarters, where the black-curtained boss agrees to meet him face to face. The episode is part twenty of The Adventures of Superman, broadcast on May 13, 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.
