What happens
Jerry and Joan, trapped inside the Magic Island, climb down an elevator shaft to escape a pursuing car and reach the sub-level power rooms. They emerge into a lower corridor and encounter a guard, and Joan uses a ray gun to put him to sleep. Their five-minute window is short, and they must shut off the island's power and escape before the guard wakes. Their plan depends on quick action at the power room controls, with the outcome still unresolved at the close of this portion.
The Magic Island, including its elevator shaft, a lower curving corridor, and the power room sub-levels beneath the island.
Characters: Jerry, Joan, Klyostra, Captain Bradford, Mrs. Gregory, Johnson
Listen for: The sound of the elevator car approaching in the shaft, and the guard's ray gun taking effect in the corridor.
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.
