Jana Skoff, star of the folk music trio "Jana and die Lausbuam", has fallen madly in love with the singer of an indie band and would like to start a new life with her. Then Alex is found dead. As Commissioner Bergmann and his partner Anni learn from their Spusi colleague Kofler, someone has insidiously blocked the vent of the oven in the bathhouse where the victim slept. Many would have had the opportunity to do this: Alex's jealous, drug-addicted ex-girlfriend and bandmate Luca, the "Lausbuam", Jana's brother Dominik and her estranged husband Hubert, as well as the shady manager Jack Riedl. And none of them mourn for the dead. While Jana's conservative parents fear for the family's good reputation and even better business, Bergmann and Anni set about "smoking out" the perpetrator.
