When ancient giants begin to reawaken in the British Isles, Hellboy is invited to join an ancient band of fellow monster hunters called the Wild Hunt and help bring them down. But an unexpected betrayal sends Hellboy after a quarry far more deadly: the Queen of Blood, first seen in 2007's best-selling "Hellboy: Darkness Calls". This newly reborn evil has her murderous sights set on all of humanity, and the only way Hellboy can stop her is to finally confront the truth about his own dark heritage.
