Anton Stadler and Verena Danner investigate the murder of Bettina Neuhaus, found beaten to death on a picnic blanket on on hike from Inn-Auen. Bettina's husband Karl-Heinz Neuhaus assumed her on a art auction in Munich, which she attended with secret lover Felix Lehmberger, but they had a row. That same night, employee Mareike Mattusch reports a break-in in Bettina's antiquities shop, where only some cash and minor items seem stolen and a key was used. Christian Bach, who rejoined the theft section, recognizes this MO, which trails to innkeeper Alfons Patzer, whose picnic programs suspiciously often are followed by robberies. Anton is unpleasantly surprised by the arrangements to house his police partner.
