Intro. In a world where vampires and werewolves hide their ancestral war between modern humans, Mary, a hungry vampire, chooses Mark, a shy boy oblivious to his werewolf heritage, as prey. Losing control of his powers, Mary attacks him in a terrifying transformation, biting his neck and triggering a confrontation that could reveal dormant secrets and reignite the conflict between the races.

Mary — the war between vampires and werewolves.
