Helga Rothe (Marianne Wünscher) was the focus of her house for many years. She helped her single daughter Iris (Karin Ugowski) and raised her grandson Mathias (Thomas Dannemann). Helga Rothe spoils Mathias and fulfills all his wishes. Since Iris married Harry Buchwald (Andreas Schmidt-Schaller), Grandma Rothe has no longer been the sole figure in the house. There is therefore often a dispute over the upbringing of the grandson. When the young family moves out, Helga Rothe tries more than ever to tie Mathias to herself. This does not require much effort, since the boy knows that he can have everything from grandma.
