The rural American west is the setting for this OVA, in which a bizarre and brutal attack on a NASA base in Arizona attracts the attention of a French secret service agent, Monsieur Lassar, when a dead CIA agent is found floating on the Seine in Paris. Lassar is convinced that these two events are related, and sets out to prove it. His investigation leads him to film star Lamia Vindaw and a vampire cult that may be far more vicious and dangerous than its eccentric exterior makes it seem.
Unfortunately the movie Vampire Wars is not yet available on HBO Max.
