The documentary-television director duo Jolán Árvai and László Sántha, while making an entertaining documentary-report montage about the rock life of the period between 1957 and 1973, were mainly curious about how and why the movement's sad metamorphosis began. What intention and what mechanism of action resulted in the withering away and slow death of progressive trends; the most vital ones becoming manipulable and commercialized? The filmmakers do not tell the answer, and they do not tell anyone. They leave it up to the viewer to decide whether they want to answer at all. Because if not, the seventy-five minutes of Rockfogyatkozás will still pass quickly. It carries within itself the possibility of a multi-part series offering an optional experience, with which several layers of viewers can be satisfied at the same time.

In the open-air cinema-like scenery domestic rock bands get time for a short movie clip each, linked by an also short musical frame-play. Each of the altogether eighteen clips is a whole film etude playing with visual-lingual associations, film ideas, revealing the back-thought of the songs, and on the whole sometimes melancholicly, sometimes ironically the hopeless, sad picture of the era can be distinguished.

The investigation of the melon affair, to remain undisclosed for thirty years, is led by Major Piroska Szabó, the secret girlfriend of Mr. Kálmán, the boss, with a charge against the policemen Lajos Endúros and Richard Wagner. Sitting on the terrace of their favourite snack bar, the two policemen, along with Sergeant-Major Badár, take an oath not to testify against each other, and to mislead the authorities by giving false evidence.

Lili is a typical girl of our time: she's lonely and tries to convince herself that this is what's good for her. But one day, she finds an old package of letters in her parents' apartment, which her mother apparently didn't want to show her at all. Of course, she doesn't hesitate much, she starts reading, and the past comes alive... an unforgettable summer in the early 1990s, when three good friends are on vacation at Lake Balaton, and of them, only Eszter wants to stay faithful to her boyfriend who left her at home, who swallowed a stake. But her plans, which she usually follows with engineering precision, are slightly messed up when she meets Gergo, easygoing, funny and has another very good quality: he plays in a band and performs with his friends on the beach in Szigliget in the evenings.
