What happens
Tarzan travels to the mountain country of the Marwatt tribe, a people of unusually tall and strong men and women. He is adopted into the tribe and is set to marry Velda, but a rival named Kalo resents him. Meanwhile Captain Marco and the sheik Ajib ben Zaman plan to capture the Marwatt and sell them as slaves, hiring Tarzan's rival Kalo to work in their camp. The story follows the Marwatt's efforts to face the slave raiders and the question of who Tarzan will marry.
The Marwatt tribe's village in the mountain jungle of Dark Africa, and the slave traders' camp in the Sudan near Fashoda, reached from Port Said.

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.
