The Hellsing organization has recently discovered that there are attempts being made to create artificial undead beings. This is happening during World War II and the leader of Hellsing fears that these creatures could be used by the Nazis as super-soldiers on the front lines. Although the technology for creating artificial vampires is still in its early stages, it has advanced enough to pose a serious threat. To stop this dangerous experimentation, two skilled agents from Hellsing have been sent to Poland. One of them is Walter C. Dornes, also known as "The Angel of Death," and the other is Alucard, an ancient vampire who is currently being forced to serve the Hellsing Organization. Together, they work to put a stop to the Nazis' efforts.
