In a series of flashbacks played in reverse chronological order it is related that in 1939, Professor Trevor Bruttenholm investigated a series of murders in Eastern Europe. Erzebet Ondrushko, a vampire who bathed in the blood of innocents to stay young, was responsible. She had sold her soul to the Queen of Witches, the goddess Hecate, and had just kidnapped the fiancee of one of the townsmen. When the search party confronted Erzebet in her castle, all members of the party were horribly killed, and Bruttenholm was left to face her alone. He tricked her into the sunlight, effectively destroying her.In the present day, an elderly Bruttenholm, who is overcome with memories of his encounter with Erzebet, takes a particular interest in a publicity stunt case in the Hamptons on Long Island. A haunting has been reported in a mansion recently purchased by developer Oliver Trumbolt, a friend of a U.S. Senator with hands deep in the BPRDs budget, and considered a low priority. Bruttenhom insists that their most advanced team should go Liz Sherman, Abe Sapien, Hellboy and junior agent Sydney Leach as well as himself to everyones surprise. Bruttenholm does not explain his motives at first. ........
