What happens
Jerry and Joan Gregory, with Mrs. Gregory and Captain Bradford, are stranded on their boat after leaving the magic island of Euclidea. Their fuel has run out, and a drum of oil they hoped to use turned out to be turpentine, leaving them helpless. A submarine arrives to tow them back to the island. Its commander comes aboard alone and tells the group that they will be taken back as prisoners, and that she will take Mrs. Gregory and Joan with her in the submarine. Jerry and Tex, meanwhile, discover that the boat is taking on water.

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.
