During their nocturnal meeting in the city park near the beach, it turns out that the young man has already married Zinochka (Ekaterina Vulichenko) – the underage daughter of schoolteacher Mariana Pavlovna.

Pyotr Matyukhin (Mikhail Filippov), investigator of the local department of internal affairs, begins to pressure the girl into confessing to the murder.

Professional photographer Andrei (Dmitry Maryanov) who supposedly made these pictures claims that he does not remember anything of the sort.

Thanks to the intervention of school director Tamara Georgievna (Olga Ostroumova), Dina returns to work and to everyday life.

School teacher Mariana Pavlovna (Elena Anisimova), from whom Dina has been renting her room since she arrived, in the light of recent events is ready to put her out on the street.
