The world-distant and absent-minded professor Jacob Jensen lives exclusively for his science and his stamps. He has no idea what is going on around him, in his own home. In the 11 years since his wife died, his capable, wise and lovable housekeeper Karen Frederiksen has, with a loving hand, managed the home for him and his 3 children. The aspiring amateur boxer Oscar and the 2 daughters Else-Margrethe and Birthe. She has shared in the children's sorrows and joys and has often lent them money when they have had dry pocket pains. She has praised and scolded them at the right times - in short, she has been in their mother's place. Both the professor and the children take her for granted. They take her services, big and small, for granted, and do not quite understand what she really means to them.
