World War II has begun and a new arsenal of weaponry is unleashed upon the world: the V-2 rocket, Spitfires, Sherman tanks… and dinosaurs. Only two women know the secret of Dinolebhaftigkeit, the process of dinosaur reanimation. Dr. Elsa Wild flees Nazi Germany to reanimate sickle-clawed therizinosaurs for the United States. Dr. Grizelda Rot stays in Germany and raises tyrannosaurs for Hitler. Battle-ready and bloody clawed, the American therizinosaurs will attack anything with a swastika. Tyrannosaurs branded with the swastika rampage through the streets of Berlin, fighting for the Fuhrer as the city goes down in flames. The therizinosaurs are coming. Tyrannosaurs fight to the death. The fate of the world hangs in the balance.
