What happens
Dantro the Planet Man and Pat, daughter of Professor Darrow, speed toward Mars to aid the Martian underground against its ruler, Marsden. On the way they are intercepted by Marsden's patrol and taken prisoner to his throne room. Marsden gloats over his plan to conquer Earth and seizes the two of them as hostages. The transcript breaks off with Dantro and Pat locked in a dungeon, facing the threat of the Marlions and wondering how they can escape.

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.
