Everybody wears glasses in the family of twelve-year old Jana, and everybody is also quite mad. Jana often has bad luck - one time she breaks her arm, another time her leg or something else. The family always visits her in the hospital, and when the girl returns home, there are always many gifts waiting for her. Upon her most recent return, Jana notices that things are out of tune between the parents and that father does not sleep with mother in the bedroom. She reveals to her older sister Zuza her worries that their parents want to get divorced. Both girls begin to act immediately, trying to find out first if the parents have someone else.
