The Changes is a British children's science fiction television serial filmed in 1974 and first broadcast in 1975 by the BBC. It was directed by John Prowse and is based on the trilogy written by Peter Dickinson: The Weathermonger (1968), Heartsease (1969), and The Devil's Children (1970) (the books were written in reverse order: the events of The Devil's Children happen first, Heartsease second, and The Weathermonger third).
Storyline
In a post-apocalyptic Britain, everyone has rebelled against modern technology (electricity, engines, trains etc) and reverted to a pre-Industrial Revolution way of life. When Nicky Gore tries to investigate the cause, she is accused of being a witch and imprisoned to prevent her spreading dissent.
