When the coffin of the German Gisela Aichinger is carried out of the apartment of the Transitus organization, the attendants have to fight their way through a crowd of people. The members of the religious association Pro Vita protest against euthanasia. Suddenly the dead man's son appears. Martin Aichinger appears confused, threatens those present and claims that his mother did not go to Switzerland voluntarily to die. That same evening, dying attendant Helen Mathys is knocked out and smothered with a plastic bag. Commissioners Reto Flückiger and Liz Ritschard first talk to Dr. Herman. The founder and director of Transitus explains to investigators how an assisted suicide usually works. The day before, the two volunteer Transitus employees Jonas Sauber and Nadine Camenisch, together with the murder victim, were responsible for carrying out the terminal care. Because the main suspect, Martin Aichinger, used force to obtain their addresses and went into hiding, Flückiger and Ritschard suspect that the two are in danger. Josef Thommen, leader and charismatic head, is also suspiciousby ProVita. Apparently he has an informant who tells him when the next terminal care will take place. Thommen seems to be fine with any means to hinder Transitus' activities. He is also by no means the morally upright personality that he likes to portray to the outside world. The Lucerne commissioners get caught between the fronts of supporters and opponents of euthanasia.
The eleventh Swiss "Tatort: Freitod" is about the attitude towards death - about voluntary and involuntary dying. The fictional organization Transitus prepares a dignified and self-determined death for those who travel from abroad. The religious group Pro Vita, on the other hand, believes that only God can determine the time of death, no matter how sick the person is. And finally there is the killing, in which a person is brutally taken from life. Delia Mayer and Stefan Gubser as well as Fabienne Hadorn as head of forensics and Jean-Pierre Cornu as police chief. Martin Butzke, Martin Rapold, Andreas Matti, Anna Schinz, Sebastian Krähenbühl and Lukas Kubik can be seen in the most important episodic roles.
