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.

All her life, 80-year-old Margot Brunner (Rosemarie Fendel) has lived with her disabled sister Wilma (Cornelia Froboess) in the apartment of their deceased mother. The grove Wilma seizes every opportunity she gets to be a nuisance to her sister. When Margot meets artist Gregor (Matthias Habich), she finally gets the courage to tell her sister that she wants to enjoy her life and get out of the house. But Wilma does not agree with this.
