Bafta-winning TV adaptation of the classic children's novel by Clive King. Barney (Thomas Sangster) is a shy ten-year-old who's spending the summer holidays with his grandparents. One day, while out walking, he is chased by the village bullies and tumbles down an overgrown quarry. There, on the quarry floor, he encounters an apparently humanoid figure with thick shaggy hair and two bright eyes. This creature turns out to be Stig (Robert Tannion), a caveman who is hundreds of thousands of years old. Gradually he and Barney learn to communicate with other. Together they forage through the rubbish dump at the bottom of the quarry, using the things the villagers throw away to improve Stig's cave. So begins a very special friendship, and a tale which has charmed children and adults alike ever since it was first published in 1963.
