What happens
Captain Bradford and Mrs. Gregory secretly move their valuables and navigation instruments aboard a cruiser that Johnson brought to rescue them on the magic island of Euclidea. Jerry and Joan, working deep in the island's lower levels, plan to take control of the Euclidean radio and power rooms. Joan uses a ray gun to stage a fake sleep on Jerry so that a guard will leave them alone, then the pair flee the guard's chamber by elevator. Hunted through the island's corridors, they decide to capture a lookout posted near an elevator and to climb down an emergency ladder inside the shaft to escape the searching guards.
The magic island of Euclidea, its lower levels, elevator shafts and control rooms, at dusk and into the evening.
Characters: Captain Bradford, Mrs. Gregory, Johnson, Jerry, Joan
Listen for: Joan's plan to use the ray gun on the guard's protected neck, and the decision to descend the emergency ladder inside the elevator shaft.
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.
