Marga Engel, the likeable and self-confident cook, has built up a new life for herself with a lot of energy and love: she works as a cook and "financial manager" in a children's home, whose little residents have taken the shrewd woman very much to their hearts. However, Marga's "favorite enemy", the slick building contractor Ohrmann, has his eye on the picturesque villa in which the home is housed. His plan: he wants to transform the magnificent building into an elegant anti-ageing clinic for a wealthy group of investors.
