At the club feast for his installation as new champion-shot 'club king' of Jork, Harald Proske is fatally shot -in Oskar's presence- with a weapon of his own class's caliber from behind a curtain veiling the killer and his retreat. Harald owned a supermarket chain and planned a Jork subsidiary, probably fatal for local shopkeepers like baker Dietmar Röper, who hoped his daughter Yvonne would succeed him with boyfriend Timo Fenne who discovered she had an affair with Harald, ignoring he still had many flirts. SOKO learns about a ten years old family feud between Röpers and Proskes. Already year-long separated fresh widow Carola Proske would have had no inheritance if he had time to divorce her. Jan observes her making suspicious payments as regularly before to a man fitting a hit-man's photograph, yet gets a surprising explanation. Timo's hose is searched, yielding ammunition and the possible murder weapon.
