Chief Inspector Karl Jäger is preparing for the birth of his grandchild, while his colleague Jasmin Stein is thrown into a passionate love affair. But Lola Kraft is also back after her maternity leave when the body of a car dealer is found in a villa. The safe is open, but apparently no money was stolen. What was so valuable that the son of a Russian mafia boss had to die?

A supermarket is robbed. Commissioner Karl Jäger, who happens to be present, shoots the robber and is subsequently suspended from duty because the attacker’s weapon is not found. The incident also plunges Jäger into deep psychological problems. As a result, commissioners Lola Kraft and Jasmin Stein are called in when two bodies are discovered during the night of a class reunion at the Calw Hermann Hesse High School. All 29 party guests are considered suspects. When the investigators find out that their suspended colleague was a former classmate, his memories help advance the solution to the case, which has its origins in their school days.

Inspectors Karl Jäger, Lola Kraft and junior police officer Jasmin Stein must solve the brutal murder of a hunter whose dismembered body was found in the middle of the forest. The investigation points to illegal arms trafficking and initially leads to the Reich Citizens' milieu. Another blood trail was also found at the crime scene...

Detectives Karl Jäger and Lola Kraft are investigating again. An inconspicuous family man saves a young woman from being raped and uses unexpected skills that not only attract the attention of himself, but also of the police. But it is not just his mysterious past that troubles the amnesiac victim, but also a killer squad. Who is after him? And what is the mystery of his past?

This time, Tatort Calw takes us to the stage, the world's greatest stage. During an amateur theater performance, a version of Romeo & Juliet "translated" into Swabian, a shot is fired according to the script. But the bullet was not a blank. The result: undertaker and amateur actor Günther Jourdan lies dead on the stage. A new case for Calw detectives Jäger, Kraft, and Hoffmann, who now find themselves confronted with a multitude of quarrels, motives, and suspects within the theater troupe. Secret affairs, property disputes, pregnancies, and personal animosities. The theater people are like a prime-time soap opera on private television. However, when the alleged perpetrator is identified, there is a surprising twist.

Because detectives Jäger and Kraft botched an unauthorized operation, they now have to face the consequences: they are demoted and placed under the command of their colleague Hoffmann. In their private lives, too, things are not as they should be. While Jäger is kept busy at night by his young children, Lola and Andreas' relationship is in crisis. The Calw investigators are really not having an easy time of it at the moment. And then there's their new case, which seems to be a tough one. When businessman Till Ritter is found dead, everything seems clear at first: suicide. But the matter becomes more complicated. Why was Ritter's daughter kidnapped? And what is his son Philip hiding? And what does the body found in a nearby lake have to do with it? The three detectives and their new colleague still have a lot of work ahead of them, because there is still a long way to go before all the questions are answered and the case can be closed...
