Overview:The Borejko family has four daughters - Gabriela, Ida, Natalia and Patricia. Most concern causes the red-haired Ida, whose unusual ideas often end badly, though the girl has the best intentions. Her father, who works at the university as a classical philologist, gives her the idea to found a group called ESD. They want to try out the theory that you are more successful if you send out more positive signals to the environment. Soon this theory will be put to the test. Ida's mother has to go to the hospital and the entire burden of household chores falls on the children.
