It features an unusually dark tone for the series, as the protagonists are faced with certain death after they are apprehended by a cannibalistic tribe in the jungle.

Ornithologist Professor Inigo Tinkle tells a less-than-enraptured audience about his most recent expedition to Africa in search for the Oozlum bird, which is said to fly in ever decreasing circles until it disappears up its own rear end.

Financing the expedition is Lady Evelyn Bagley and the team are led by the lecherous Bill Boosey and his African guide Upsidasi.

Soon after the journey starts, a gorilla terrorises the campsite, and the travellers realise they have ventured into the territory of the "Noshas", a tribe of cannibals.

On the first night of the expedition, Lady Bagley reveals that she is there to find her long-lost husband Walter and baby son Cecil, who vanished twenty years before on their honeymoon, whilst out on a walk.

As they wait to be put to death, they are rescued by the all-female Lubby-Dubby tribe led by Leda from the Lost World of Aphrodisia.

Lady Bagley is resentful of this work the men have been given and taking over control from her husband, ensures the mates assigned to them are the tribe's least attractive women.
