Rich playboy Hubertus Kalow identifies the man who died when his 'datscha' (holiday cabin) exploded but whose corpse was dumped in the lake as Bernd Grossmann, the slick organizer of speed-dating for seniors with wife Sybille, but Hubertus may be the intended target. The gas heating was clearly sabotaged. Kalow's neighbor Kurt Wölffer was a bitter opponent. Slick Hubertus serially seduced elderly women in the speed-dating, only to drop then as easily, after trying further fraud or cashing gifts, maybe even Sybille.
