What happens
Dan Tro, the Planet Man, and Pat Darrow, daughter of Professor Darrow, have been imprisoned in the dungeon of Marston, ruler of Mars. Slats, an Earthman engineer, secretly sends them a bottle of gas meant to stun the Marlions, the beasts of the arena. Dantro and Pat use the gas, escape the arena and flee into the dangerous jungle of Mars. Marston, convinced that someone betrayed him, interrogates his guards and the captured helper, and he hints at a plan to kidnap two children to force Professor Darrow's cooperation. Dantro and Pat, pursued by the mindless outcasts of the Martian mines, search for a clearing where they might be safe.

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.
