Experienced judge Lena Kalbach works at the district court in Frankfurt, the capital of Hesse. She is a woman with moral principles - and when she sees them violated, she doesn't take her legal duties too seriously. For example, when the shrewd lawyer Teddy Klein succeeds in getting a client acquitted using shady methods. Outraged, Lena refuses to accept the verdict. As punishment, the rebellious judge is transferred from the district court to a local court. She is immediately transferred to her old hometown of Fulda in eastern Hesse, of all places. For Lena, this is a professional and social relegation, as she left her hometown 30 years ago "because of the cramped conditions". Her grown-up daughter Nike, who works as a public prosecutor at the local court, lives here with her husband Johannes and their two children Clara and Emanuel.

Two fathers are fighting for a child: Franz Bergen, head of a church choir, wants to fight the right of access to the young son of the pub René Dörfler. At first, Judge Lena Kalbach does not allow the lawsuit - until it turns out that Bergen, as a sperm donor, is the biological father of the child. A delicate case for which Lena has to find a solution with great tact. But she is also personally affected by the issue of fatherhood: Her adult daughter Nike finally wants to know who her father is. In the third part of the popular TV series, Michaela May again plays the smart judge Lena Kalbach.

Ex-judge Lena Kalbach has to represent a Catholic priest, of all people, in her first appearance as a lawyer. The priest Lukas Schloss has embezzled a large sum of money and is facing a prison sentence and expulsion from the church. However, Lena discovers that the young priest had good reasons for his illegal actions. The lawyer wants to help him, but it's a difficult task: her husband Friedrich, of all people, is representing the church in this sensitive matter. In this episode of the family series, Michaela May, alias Lena Kalbach, once again amazes viewers with a legitimate form of legal malpractice.
