When women lost their tails

Filli (Senta Berger) and the other cavemen from "When Women Had Tails" are living a carefree, if boring life inside a dinosaur skeleton. But when conman Ham (Lando Buzzanca) introduces them to the concept of currency and economics, their lives fall apart. On top of that, Filli starts to fall in love with Ham...
