Jewish movie producer Chris van der Kamp was fatally stabbed in his Amsterdam office editing room. The murder weapon was stabbed while he still lived by an employee, Keizer's sister Yvonne, who brings Appie the bloody knife at home. Unlike Vledder, who once flirted with her, Keizer must abstain from field research, but the medicines he brings her are used for an OD suicide. Chris was hated by his son Koen van der Kamp, who he neglected like his late mother during her fatal cancer and was failing to keep his promise of supporting Koen's directing debut. Koen has an affair with Chris's second ex. Chris was undesirable to the parents of his third bride to be, a movie critic, slept with Yvonne and had a vicious conflict with director Olof Baltus.
