In a side valley of the Ahr, Heinrich Genenger operates a private cemetery. Those who wish to be buried according to obscure or obscene rites, which cannot be accommodated by German cemetery offices, are welcome here. A similarly private beauty and psych clinic deposits so many corpses that Genenger points out to a buddy: Baltasar Matzbach, according to one of his so-called friends, "a mix of Falstaff and Garfield, unleashed on humanity as a hobby detective." Together with his companion Jorinde, a witch, and the Chinese martial artist Felix Yü, Matzbach sets out to dig and snoop around. A mysterious dog killer is on the loose, a bad local poet is causing trouble, the government bunker of the Bonn Republic is nearby, and how is all of this supposed to fit together?.
