What happens
Jerry and Joan find themselves aboard the Euclidean submarine, which stands upright in the water to meet Johnson's boat. Johnson's vessel fails to heed the submarine's signals to stop and come about, and the commander prepares to pursue and take it. Jerry and Joan are held in place by the commander's control over them, and a radio contact with Johnson is attempted to warn him. The episode is part of the Magic Island series, and the original air date and cast are not given in the transcript.
Aboard the Euclidean submarine near Magic Island, where it stands on end at the spot set for meeting Johnson's boat.
Characters: Jerry, Joan, Johnson, Captain Bradford, G-47, Tex
Listen for: Johnson's silence on the radio as the submarine commander threatens his boat, and Bradford's urgent call for him to answer.
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.
