In the idyllic English town of Sanctuary, witches have lived peacefully as valued members of society for hundreds of years. Sarah Fenn is the town's resident witch, on whom the town relies to solve their problems when conventional remedies fail.
When a local teen rugby star dies tragically in an apparent accident, his death exposes a terrifying undercurrent of suspicion and fear towards Sarah and her teenage daughter. The rugby star's mother, once Sarah's closest friend, is wracked with grief, and launches a witch hunt to avenge her son's death.
