n 1795, Dr. Victor Frankenstein (Aden Young) creates a monster (Aaron Eckhart), and then rejects it. In a fit of rage, the creature kills Frankenstein's wife, Elizabeth (Virginie Le Brun), and Victor chases it to the Arctic to get revenge, but succumbs to the weather. The being buries its creator and is then attacked by demons before being rescued by gargoyles Ophir and Keziah, who bring it before the gargoyle queen, Lenore (Miranda Otto), and their commander, Gideon (Jai Courtney). Lenore explains that they were created by the Archangel Michael to battle demons on Earth, and names the creature "Adam", inviting him to join them, but he declines and departs after being given gargoyle weapons that allow him to destroy demons.
Throughout the centuries, Adam fends off the demons that pursue him. During a modern-day confrontation at a nightclub, a policeman is killed. While Adam is summoned by the gargoyles once more, the demon Helek (Steve Mouzakis) reports that Adam is alive to his leader, demon-prince Naberius (Bill Nighy), who is disguised as billionaire businessman Charles Wessex, and his right-hand man, Dekar (Kevin Grevioux). Wessex has employed scientist Terra Wade (Yvonne Strahovski) to conduct experiments with reanimated corpses, and sends a group of demons led by his most formidable warrior, Zuriel, to attack the gargoyles' cathedral and capture Adam so he can unlock the secret to give life.
