Vampire Bat [Blu-ray]

When corpses drained of blood appear in a village, town elders suspect a vampire is on the loose. Policeman Karl Brettschneider doubts the existence of vampires, but Dr. Otto von Niemann argues to the contrary. Fingers point at the village idiot, Herman Gleib, but after local vigilantes get him out of the picture, the killings continue. Brettschneider tries to keep a cool head as he searches for possibly supernatural answers.
