Some of literature's most terrifying characters, including Dr. Frankenstein, Dorian Gray, and iconic figures from the novel Dracula are lurking in the darkest corners of Victorian London. Penny Dreadful is a frightening psychological thriller that weaves together these classic horror origin stories into a new adult drama.

Rooted in the conflict between characters connected to the deity Santa Muerte and others allied with the Devil, this saga explores an exciting mix of the supernatural and the combustible reality of 1938 Los Angeles, a time and place deeply infused with Mexican-American folklore and social tension.
