Plot & Details
This situation sex comedy falls somewhere in between vulgarity and burlesque. Ulli (Giuliano Gemma) and his six cave-dwelling cronies try to learn all the conveniences of their era -- like building fires, using the wheel, and perfecting the use of tools and weapons. A fire engulfs their tiny island and the men are forced to take a raft to the unknown mainland. There Ulli meets Filli (Senta Berger), and he spends his time trying to make her his monogamous girlfriend by discouraging others who desire her for their own. Ennio Morricone provides the music to this feature, which was a surprising box-office hit in Italy.
