Plot
British explorer David Marchant, Colonel Hammond and a guide are pursuing a wounded leopard on an African safari. David decides to find the beast and put it out of its misery before nightfall.
Walking some way, he passes various trees with a picture of a white rhino, but ignores them. The leopard attacks him and he shoots it dead, whereupon David is ambushed and captured by a primitive tribe. They accuse him of disturbing the spirit of the white rhinoceros and take him to their leader's temple. As the high priest makes his decision, David notices a large, ancient stone statue of a white rhino and realises this is what the tribe worship. Interested, David reaches out to touch it. Just as he is about to be killed for his trespassing and disturbing the spirits, David touches the statue and there is a flash of lightning that opens a giant crack in the cave wall. David flees through it.
David finds himself in a lush paradise jungle within a large valley. He hears a noise, and encounters a terrified fair-haired woman. David tries to help her, but the woman runs off. David follows her, but they are both attacked by dark-haired women. David is escorted with them to their village, while the fair-haired woman is bound and taken with them. As they reach the outskirts, David is astounded to discover another white rhino statue.
Entering the settlement, David finds that the fair-haired women serve the dark-haired women, who themselves are ruled by the beautiful, dark-haired Queen Kari, who immediately takes an interest in David and chooses him as her mate, but he is appalled by her cruelty and spurns her advances. Angered, Kari orders her guards to throw David into a windowless cell. Coming to his senses, David finds the same woman he encountered earlier, revealing her name as Saria. When David asks if Saria's people have ever fought back, she replies that Kari is protected by the Devils, the guardians shielding the people from the "cruel world outside". In return, one of the fair-haired women must be taken as a thanksgiving for protection.
David is moved to where the other men are, in a cave and now living in fear of Kari. At mealtime, an elder tells David of how it all began; their ancestors moved into the area and hunted the white rhino to extinction. This done, they erected a false image to convince others that they still existed. In doing so, they offended their gods, and the legend of the white rhino was born. The elder explains they were sent a tribe of "dark people", who came to this land seeking protection and enslaved them. The only protection Saria's people had was the lie that the white rhino protected them, until a slave girl escaped and told them of the lie. As a result, the men were enslaved and the slave girl was made their queen, Kari. The tribe will only become bonded by the spirit again when the false idol is destroyed.
As time passes, a "Devil" chooses Saria as the next bride of the white rhino. David urges the men to join forces with the fair-haired women against the dark people. Escaping, the men disrupt the ceremony as the rhino-masked "Devil" is about to take Saria. David jumps the "Devil" and unmasks him as an African man. David frees Saria as more rhino-masked "Devils" emerge from the jungle, but the men and allied women pursue them, unaware they do not know the jungle as well as they do. A battle breaks out between the two tribes in the jungle. Kari sets out through the battle to kill David. Suddenly, there is an almighty roar and both tribes see a white rhino. Despite Kari telling the tribes it is their god, the beast charges and impales the false idol, Kari. The creature begins to drive out the "Devils" and disappears into the jungle.
David takes Kari's white rhino brooch and offers it to Saria, who then refuses it, saying that the "Devils" will not be returning. She goes on to say that the legend is partly fulfilled and she heads over to the white rhino statue. David tells her that he will not leave her, despite Saria telling him that her world is not his. David confesses his love for Saria, but she moves away and tells David that her love for him will always remain. She leaves David alone in the rain, along with the statue of the white rhino. As if hypnotised, David touches the white rhino's horn as lightning strikes.
