"The Witchfinder" is a British comedy series set in 1647, when people live in constant fear of witchcraft. Puritan Christianity, deeply rooted in superstition and a readiness to scapegoat outsiders, has instilled in people a sense of paranoia and suspicion. Few remain safe. During this time, witch-hunting is thriving. Everyone wants to earn a reputation as an expert in witchcraft and gain universal recognition.
