Heute fängt mein Leben an: For a lifetime, Hedi Ohlsen subordinated her needs to the family. She raised a child, took care of the house and learned the unloved profession of dental assistant for the sake of her husband Johannes. And although John has left her for a younger one, Hedi still cares for her elderly mother-in-law Agnes. As this now blesses the time and Hedi finally wants to start her own life, suddenly her pregnant daughter Leonie is attacking at the door. She has quit, no money and no father for the child Hedi is to raise for her. Is the dream of late freedom back?
