What happens
Clark Kent, a reporter for the Daily Planet, is at San Miguel penitentiary, where a riot has trapped the convict known as the Wolf and his accomplice Kino in the dining hall. Reporter Lois Lane has been taken hostage by the Wolf's gang. Superman, the costumed hero whose identity is Clark Kent, has already quelled the riot in the yard and now searches the prison for the two men and for Lois. The Wolf's men hold the steam plant with live steam and an escape tunnel. This episode is from the Adventures of Superman radio series, first broadcast on March 20, 1940.

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.
