Output: The Ulam are a tribe of CroMagnonlooking people who possess fire in the form of a carefully guarded small flame which they use to start larger bonfires. Driven out of their home after a bloody battle with the apelike Wagabu, the Ulam are horrified when their fire is accidentally extinguished in a marsh. Because the tribe does not know how to create fire themselves, the tribal elder decides to send three men, Naoh, Amoukar, and Gaw, on a quest to find fire. The trio encounter several dangers on their trek, including an encounter with the Kzamm, a tribe of Neanderthallooking cannibals. The Kzamm have fire, and Naoh, Amoukar and Gaw determine to steal it. Gaw and Amoukar lure most of the Kzamm away from their encampment. Naoh kills the remaining warriors, but not before being bitten on the genitals by one, which causes him agony. The three Ulam take the Kzamm fire and prepare to head home. A young Homosapienslooking woman named Ika, who had been a captive of the Kzamm, follows them, seeking protection. She makes a primitive poultice to help Naoh recover from his injury. Later, Amoukar attempts to have sex with Ika. She hides near Naoh, who then demonstrates his claim on her by mounting her in front of the other two males. Ika soon recognizes that she is near her home and tries to persuade the Ulam trio to go with her. When they refuse, she leaves. At first Naoh continues without her, but finds he cannot stop thinking about her. He turns around, followed by the reluctant Gaw and Amoukar. After Naoh leaves the others to scout a village, he is trapped in quicksand, nearly sinking to his death, but is discovered and captured by the Ivaka — Ikas tribe. At first, Naoh is subjected to several forms of humiliation by the Ivaka. He is forced to mate with the highstatus women of the tribe, who are large and bigbreasted. The petite Ika is excluded by her tribe, and when she attempts to lie near him later that night, she is chased away. The Ivaka soon demonstrate to Naoh their advanced culture: the ability to make fire. Gaw and Amoukar find Naoh among the Ivaka. They try to rescue him but Naoh has come to identify as an Ivaka. At night, Ika helps them knock Naoh unconscious and escape the camp. The next day, Naoh washes off the Ivaka body paint. He tries to mount Ika again, but she teaches him the more intimate missionary position. Before they can reach their home, the three are beset by rivals from the Ulam tribe, but are able to defeat them using a superior weapon technology in the form of atlatls which they had stolen from the Ivaka. Finally rejoining the Ulam tribe, the group present the fire to the delight of all. But during the ensuing celebration, the fire is accidentally again extinguished. Naoh tries to create a new fire as hed seen in the Ivaka camp, but after several failed attempts, Ika takes over. Once the spark is lit, the tribe is overjoyed. Months later, Naoh and Ika prepare to have a child.
