This is pretty standard jungle fayre with Buster Crabbe leading the cast as a group of explorers try to find the legendary "City of the Dead" deep in the African jungle. This is a largely under-resourced effort peppered with plenty of interesting animal archive (not always played in real time!) as the team have to combat the natives, disease and some hungry lions and snakes as they track down a city that bore a starting resemblance to Angkor Wat. Crabbe himself is not involved in their trek, he is a local doctor trying to obtain a serum that will help the local population fight off disease. His attempt to retrieve this medicine from a sunken wreck allows him to get his shirt off and offers us a brief "Tarzan" impression, but for the most part the rest of this is all just a bit basic and roughly hewn together, with plenty of shrieking from the damsel in distress Shiela Darcy and an ending that sort of peters out rather than delivers anything.
