Sixteen-year-old students of a grammar school are supposed to write essays on "Love". The class best student Andrea (Jaroslava Schallerová) writes about a patriotic love to a country as she has no experience with a partner love. She has been living alone with her divorced pretty mother Eva (Milena Dvorská), a dentist, for many years. Recently, however, Eva met her former school-days love at a graduates' party, nowadays a famous hockey goalkeeper Brukner (Frantisek Velecký). Also his marriage fell apart; he leaves the national team and decides to leave Prague for his home town and to share flat with Eva. He takes with him his son Petr (Oldrich Kaiser), in Andrea's age, who gets his last chance to finish a grammar school in the town.
