Tomorrow is Alice's sixteenth birthday and her classmate Aleš, in the words of his grandmother, "preluded on the wall". On the fence opposite the family home, the words "I love you!" suddenly appeared. The inhabitants of the house begin to search for its originator. Is Alice the only one to whom the inscription could belong? What if little Popeye was practicing his handwriting? Or could it be Dad's confession to Mom? What about the uncle who only has eyes for the lady next door? It's not only the young who are foolish. All in the same house and everyone is suspicious... Who wrote those two beautiful words and to whom?
