What happens
Clark Kent and Jimmy Olsen investigate a plot by a secret hate group, the Knights of the White Carnation, against foreign-born players on the Metropolis High School basketball team. After a riot breaks out at the school, Clark learns that the group has spread poison pamphlets among students and that a millionaire, Charles Canfield, may have been murdered to silence him. A student identifies one of the agitators, a tall thin man with a pasty face. The episode is part of The Adventures of Superman radio series, and this instalment's broadcast date is March 6, 1947.

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.
