What happens
Mrs. Gregory and her small group of friends are captured again by a Euclidean submarine and towed back toward the Magic Island. Tex Bradford and Jerry Hall are aboard their boat, which is taking on water through a hole cut by a Euclidean guard who was their prisoner. Tex and Jerry worry about what the Euclideans want with them, and Tex admits he would give up the real formula before letting them take it. The submarine commander arrives to question them, and a hidden guard uses a ray gun to put some of the crew to sleep. Jerry and Tex plan to overpower him, and the boat's skipper prepares to act. The series is Magic Island.

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.
