London, 1888: Jack the Ripper begins his reign of terror. Miss Sarah Bain, a photographer, supplements her meager income by taking illicit boudoir photographs of the town's local ladies of the night. But when two of her models are found gruesomely murdered within weeks of one another, Sarah begins to suspect it's more than mere coincidence. Teamed with a motley crew of friends—including a street urchin, a gay aristocrat, a Jewish butcher and his wife, and a beautiful young actress—Sarah delves into the crime of the century. But just as she starts unlocking the Ripper's secrets, she catches the attention of the local police, who believe she knows more than she's revealing, and the Ripper himself, who's bent on silencing her for good.
