The Midwich Cuckoos is set in Midwich, a small English commuter town that is liberal and aspirational, populated by nuclear families and affluent high streets. A place where nothing much happens – and for a very good reason. That is until the twilight hours of a summer’s day when a sleepy corner of Midwich is plunged into panic. People pass out on their feet without warning, without reason. Anyone who tries to enter meets the same fate. And nobody can understand why. When the mysterious blackout is lifted, life for those affected returns to apparent normality – except every woman of child-bearing age inside the zone has suddenly and inexplicably fallen pregnant. As news spreads and tensions simmer, it is up to gifted psychotherapist Dr Susannah Zellaby to help support those affected through the emotional wilderness.
