London's dockside is threatened by the twin terrors of a plague leaving bodies covered in tentacles and a slasher killing women in the night. Desperate for answers after the wrong man is executed for the murders, a group of Londoners holds a séance to contract the supposed killer, and his story of a girl born of the sea who has brought a terrible curse only brings them more questions.

Mike Mignola and Troy Nixey's acclaimed standalone series is colored for the first time by Eisner Award winner Dave Stewart.
