A man is killed by a mysterious creature -- his body drained of blood. A woman is savagely attacked by a ferocious beast -- her jugular ripped out. Bat wings flutter across the moon and the howl of a wolf echoes through the streets, for the creatures of the night have risen from the grave, and humanity's only salvation is the combined might of The Last Son of Krypton and The Dark Knight Detective. Blood will run red when Superman and Batman face off against vampires and werewolves for the fate of the entire DCU!
