What happens
Jerry Hall and Captain Tex Bradford sail with Mrs. Patricia Gregory in her private yacht in the South Seas, searching for an island where her lost daughter may be living. The yacht is stopped by a bank of fog that holds its bow fast while every instrument on board goes dead. Jerry, Tex and Patricia debate what could be causing this, and Tex prepares his fog-penetrating device to see what lies beyond the grey wall. The series is Magic Island, and this episode is the fourth installment of the program.

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.
