Dr. Hans Neumeister is a senior civil servant and lives as a widower with his four children. His domestics never stay long at his house, and once again he is searching for a new housemaid. But the children wish for a woman that will stay – as the new wife for their father. So they search by themselves and advertise for a woman to marry him. Out of all the candidates they choose the right one, but Neumeister of course is mistaking her for the new housemaid.
