Frank Martino worked as the handyman for Ashtenburrow Heights, living in the bottom flat with his wife and young daughter. After a routine cleaning of an abandoned apartment, he and his family are transported to Culvert, a shadowy city besieged by vampires, ghouls, and cultists. Now his wife has a craving for fresh blood, and a crazed priest thinks his thirteen-year-old daughter is a demon’s ‘eternal bride.’

Armed with a cursed talisman, pure pigheadedness, and a sword, Frank joins forces with a local witch hunter. Like always, things need fixing, and he'll be the one to fix them.
