The B.P.R.D. crew investigates the site of a hundred-year-old magical ritual and Hellboy breaks into  the secret library of a dead necromancer.

A demented surgeon attempts to cure vampirism by creating greater horrors, and a perverse inquisitor reveals his own dark secrets, as Baltimore pursues the scarred vampire that he blames for all of it.

Agent Johann, the ectoplasmic man, leads a special task force through the monster-filled Northwest woods in order to hunt down and kill the man he blames for leaving him a disembodied spirit. In the Southwest, agent Devon and the psychic crust punk Fenix form an uneasy alliance in order to escape a horde of giant bat-faced monsters.

A mutated Abe Sapien fights carnivorous monsters crawling out of the desert sand, a fortified militia that's walled Phoenix off from the rest of the world, and a vicious zombie swarm, while a mad necromancer rises over the monster-infested ruins of Seattle.

As Liz Sherman fights for her life in Utah, the BPRD plans an assault into the no man's land that used to be New York City, and the young psychic Fenix faces a monster-worshiping cult at the Salton Sea.
