Tells the story of Ug and his parents who live in the Stone Age and Ug's constant quest for improving their family life.
The Stone Age means stone duvets, cold food, an even colder cave and - worst of all - stone trousers! Ug, being an inventive and inquisitive boy, has wonderful ideas for improving family life.
Alas, his parents and his friends fail to understand his inspiration about heating, cooking, boats and balls that actually bounce. And Ug who is touchingly unsure of himself, can't always see the practical purpose of his creations - his round stone that rolls down the hill is great - but what is it actually for?
So often Ug comes tantalisingly close to his ultimate goal only to find that there are obstacles that even a boy genius cannot overcome. But no one can destroy his dream...
