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.
