What happens
Captain Bradford and Mrs. Gregory are back on their yacht after it was taken into a submerged lock beneath Euclidea, the Magic Island. Their captor G-47 has allowed the island to rise and the yacht to return to open water. Meanwhile Johnson's boat, which has run out of fuel, is being towed toward the island by a submarine commanded by G-47, with Jerry and Joan aboard. Bradford relays orders to Johnson by radio, and the crew of the yacht reflect on their situation. Its monitoring of the signals and its talk of the magnets and the coming arrival set the tension. The story is in the Magic Island series, and the episode is told in a serial radio drama style. It is part of an ongoing storyline.

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.
