What happens
Captain Tex Bradford, Mrs. Gregory and Jerry are stranded with the Gregory yacht inside a submerged lock beneath the hidden island of Euclidean, which lies fifty feet under the South Pacific near a battle fleet holding maneuvers. Jerry and Mrs. Gregory rig the broken aerial to the anchor chain so their radio can reach Johnson's boat. Johnson's coded messages suggest a pigeon carrying a warning is on its way, and Bradford realizes the island's scientists have located Johnson's position. Bradford then orders Jerry to report to a submarine, while Joan is also taken aboard, leaving Mrs. Gregory worried for them both. The episode is from the Magic Island series.

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.
