What happens
Superman battles Henry Miller, a fanatical young Nazi who has gained atomic power from kryptonite and plans to destroy the dam above Metropolis. Miller attacks the reservoir with green lightning while police and soldiers guard the river and canals. Superman launches himself at Miller in the night skies, and the two fight a fierce aerial and ground battle through the moonlit hills. The episode is part nineteen of The Adventures of Superman, a radio series, first broadcast on 1945-12-03.
Metropolis and the hills above the city, including a billion gallon reservoir, its dam, and the North Canal, at night.
Characters: Superman, Henry Miller, Inspector Henderson, General Miles
Listen for: The closing moments, when Superman and Miller fall from the sky toward the North Canal, and Inspector Henderson and General Miles find Superman alive and speak with him.
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.
