The former professional footballer Alex Brehm has taken care of his daughter Charlie since the accidental death of his wife. The girl suffers greatly from the loss of her beloved mother, but is an avid footballer and finds distraction from her grief, at least for a short while. Also, she is "completely the daddy" - until Alex learns one day after a blood test of his daughter that neither he nor his deceased wife Charlie's biological parents can be.

Franziska Luginsland protects the girl Jolanda from the police and helps him to find his mother.
