Inspectors Anna Janneke (Margarita Broich) and Paul Brix (Wolfram Koch) are confronted with the death of six women and men, all of whom took part in a psycholysis session and died during the therapy session. As part of their investigation, they come across Dr. Adrian Goser (Martin Wuttke), a controversial psychoanalyst and the sole survivor. Goser is known for conducting a particular form of psychoanalysis that uses psychedelic drugs to achieve absolute self-knowledge. While Brix considers Goser to be an impostor who consciously steers his patients into addiction, Janneke remains ambivalent about his therapy.

Is this an attack by the actual perpetrator, who now also wants to execute the last victim? And what does the performance artist Ellen (Aenne Schwarz), who disappeared a year ago, have to do with the case?
