What happens
Magic Island follows Jerry and Joan, who are held aboard a submarine commanded by a woman and forced to lure Johnson's rescue boat to the island. Mrs. Gregory and Captain Bradford wait with G-47 in the control chamber as the submarine rises to meet Johnson's ship. Jerry has been made to send radio messages to Johnson, and Cleostra keeps Jerry and Joan under her control. The submarine surfaces, and the two prisoners prepare for a boarding.

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.
