Mia Brake and her archaeometrist father Adam move to Milbury, a village framed by an ancient stone circle.

But all is not right in Milbury. The stones emit a strange power. The villagers are eerily happy, greeting each other with the unnerving phrase “Happy Day!” And at the village school the other children can solve incredibly complex mathematical problems.

As one-by-one her friends join the Happy People, Mia must uncover the secret of the stones.

Children of the Stones is a new adaptation of the cult 1977 television series – described by comedian Stewart Lee as ‘the scariest programme ever made for children.’
