Tale of prehistoric survival and love between a male and a female belonging to opposing tribes that happen to be at slightly different stages of evolution.

Tumak, member of the prehistoric Rock tribe, is exiled and makes his way to the more peaceful Shell tribe, where he is taken in and taught manners by the lovely Loana. Forced to leave the Shell tribe for fighting, Tumak, along with Loana, return to the Rock tribe, where Loana shows them the error of their brutal ways--until the volcano erupts.—Doug Sederberg <[email protected]>

A group of hikers are caught in a rainstorm and go into a cave for shelter. While in the cave they meet an archaeologist who is studying some of the paintings on the wall. The archaeologist then entertains the hikers with a story he has been able to interpret from the paintings. He tells the story of a young caveman named Tumak, the son of the chief of the uncivilized Rock tribe, and Loana, the daughter of the chief of the more peaceful Shell tribe. He tells of their struggles for survival and how the two tribes eventually became one.—Brian Washington <[email protected]>
