She does not know, however, her father is not going to return to them, as he loves a young girl Eva whom he is going to marry as soon as possible. Before the set wedding date Eva decides to meet Jana and introduce her and Milan to her parents. She considers her mother's birthday a good occasion. A common encounter in a gamekeeper's house does not turn out up to Eva's fancy. The parents give the visitors a constrained or even cold welcome. They do not like Eva destroyed a marriage with a child. Also Eva's sister Olga is strangely impervious. Only Jana enjoys the new interesting place with Olga's son Arnošt. Everything suddenly turns different when Jana learns from Arnošt Eva and her Dad are going to marry. To calm the unhappy girl, the boy tells her about his and his mom's sorrow - also his father left them for another woman. Jana runs away from the gamekeeper's house and goes home alone by bus. Olga, touched, reproaches Eva that she behaved the same way as the woman who took her husband away from her. Milan feels unpleasant in Eva's parents' house and when he learns about his daughter's runaway, he sets out for her together with Eva. They run out of petrol on their way and have a row. Milan leaves Eva in a stuck car and goes back to Prague by hitchhiking. He waits for Jana at the bus station and promises he will never tell lies to her any longer.
