Niedernussdorf is a small, tranquil village in Lower Bavaria, not far from Straubing. There has never been a murder here, not as long as the people of Niedernussdorf and their police chief Gisela Wegmeyer can remember. Suddenly, a severed male finger appears in the middle of the idyll. Florian Lederer, an ambitious young chief inspector from the Straubing police department, arrives on the scene. Lederer proves that the finger, which was carried through the village by a rough-haired dachshund, was originally bitten off by a pig. He assumes that an old man in Niedernussdorf was fed to pigs. Lederer is determined to solve the murder, while Gisela firmly believes it was an accident..
