Anton is sick and his mother calls the country doctor Dr. Stöbermann. Anton realizes with horror that Stöbermann is also a vampire hunter. Meanwhile, Bauer Hering makes a scarecrow out of Rüdiger's cloak and places it in the field. Anna discovers this on her way to Ottenbüttel and now believes that her brother is no longer alive. Since Stöbermann takes a tour with his Dalmatian Brutus every evening to track down vampires, he finds Anna crying on the side of the path. Anna can convince Stöbermann that she has just got lost and is looking for her boyfriend Anton. Stöbermann takes Anna to the Hering-Hof and Anton can warn her about Stöbermann just in time. But a little later Anna, Anton and Stöbermann meet Rüdiger, who fled from a tree in front of Brutus.
