The interesting thing about the film is that there were two versions of it. At the time the film was made, there were only two TV channels in Hungary, and this gave the creators the idea for the dramaturgiai game: at the time of the presentation, the Hungarian TV-1 and Hungarian TV-2 channels started the two versions at the same time. If there were scenes where the two versions differed from each other, they were indicated in the lower left corner of the picture, in which case the viewer could decide for himself which version he wanted to watch next, he could freely choose between the two channels during the movie, without losing it thread of the story. The plot also takes a different turn in several places: for example, in the first version Otto Pál is shot and he learns of the death of his love in the hospital, while in the second version he is called to the police station and learns the tragic news there, and in the first version the two detectives together interrogates the murderer, while in the second version only the female detective does the interrogation, because the man is then looking for the decisive evidence. In later iterations, the two versions were broadcast on two separate days.
