 In this comedy, Atouck (Ringo Starr) becomes leader of the misfit cavemen. Disgraced and cast out of his tribe for lusting after Lana (Barbara Bach), the mate of tribe s head muscle man (John Matuszak), Atouck stumbles along gathering other misfits and learning a bit about the world outside of his cave. Eventually he and friends Lar (Dennis Quaid), and Tala (Shelley Long) learn the secrets of fire, cooked meat, and how to defend themselves from the brutal, yet very stupid dinosaurs.
