What happens
Tarzan learns that Jane Porter has been kidnapped by pirates and taken aboard their ship, the Arrow. He swims out alone to reach her, and from a cabin porthole she throws him a rope of sheets so that he can climb aboard. Together they free Captain Tracy, who has been imprisoned, and the three take refuge in the wheelhouse. Snipes, leader of the mutineers, cuts loose a boom that smashes through the wheelhouse, and the three are forced into the sea. Tarzan carries Jane to shore through the storm while her father, Professor Porter, and the others struggle in a small boat, searching the dark water for them.

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.
