More than half of this labored mess of a story was spent in describing the sexual obsessions of multiple characters. During German Carnival Season "anything goes", which apparently meant that the Tatort team had to join in the frivolities. Strangers and old acquaintances taking liberties with anyone out to celebrate on the streets, in bars, and in hotel rooms.
I don't recall another Tatort episode where the actual murder happened so late in the story. It's a wonder I was still watching, since this was such a low quality production. The casual sex theme was really taken to new heights, almost to the level of soft porn. A low caliber psycho drama perhaps, a good crime drama, hardly. This one was a real dud!
