'Die, you pig!'. The words are emblazoned on the wall of school principal Höpfl's home for all the villagers to see. Soon after, this very man is found lying dead as a doornail on the train tracks. Franz Eberhofer, the local policeman in the sleepy Lower Bavarian province of Niederkaltenkirchen, suspects murder. And the prospect is one that does not entirely displease him, as this backwoods offers very little excitement other than the fantastic meals with his cooking-obsessed Grandma or the constant stress with his Beatles-loving Dad. He is supported by Rudi Birkenberger, now a department-store detective but previously with Franz in the Munich detective squad until both were suspended. The Höpfl case gets even more tangled when a second corpse is found, that of a drug-addict hustler with whom Höpfl had been in contact. Franz must also cope with the fact that his Susi is having an affair and he thinks the lover is the Thai offspring of his estranged brother, who is supposed to be their babysitter.
