In 1890 England a doctor, in order to cure his wife's "sick mind", injects her with snake venom. She later gives birth to a daughter the villagers begin to call "The Devil's Baby". They soon burn the family's house down. Years later a Scotland Yard detective is sent to the village to investigate a rash of deaths that are caused by snakebite.
