Disgraced and cast out of his tribe for lusting after Lana, the mate of the tribe's head muscle man, Atouk stumbles along gathering other misfits and learning a bit about the world outside of his cave. Eventually he and friends Lar and Tala learn the secrets of fire, cooked meat, and how to defend themselves from the brutal, yet very stupid dinosaurs.

Centered around a television station which features a 1950s-style sci-fi movie interspersed with a series of wild commercials, wacky shorts and weird specials, this lampoon of contemporary life and pop culture skewers some of the silliest spectacles ever created in the name of entertainment.
