What happens
Tarzan leads an expedition into the Belgian Congo to search for Brian Gregory. Gregory's father and sister travel with the party, and Tarzan's companions include Larsen and Donald. Wolf, a member of the group, is found drugged on the morning after a night at the river camp, and Tarzan works to revive him. Later Wolf is seen approaching the native witch doctor's shelter carrying a black snake whip, while Helen and Margaret sew nearby and Tarzan and the others return from bathing.

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.
