What happens
Clark Kent and Lois Lane, reporters for the Daily Planet, are working with editor Perry White on an expose of corruption in the district attorney's office, using facts supplied by former assistant DA Ralph Remson. An invisible man has threatened them, warning them to stop publishing. When the newspaper's presses are started, a bomb is discovered hidden inside one of them, and the staff has only two minutes to find it before it detonates. Kent must decide how to deal with the device to protect the presses and the people in the building. Afterward, the staff takes their evidence to the mayor, where the invisible man again interrupts with a warning. This is the third part of the 1940 episode of The Adventures of Superman.

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.
