Spring 1942. Moscow schoolgirl Katya is corresponding with a cadet of the naval school Kostya, who is unknown to her. When sent to the front, his echelon must pass through Moscow, and they have a chance to meet ... Our days. Muscovite Katya, a talented violinist and a wild child, without realizing it, begins to follow in the footsteps of the history of Katya and Kostya, her peers from the war years. Will she be able to finish an amazing teenage love story that began years ago?

In the modest apartment of a former school teacher and insect expert, Zyablikova, the lights are turned off. This happens right on the eve of a television shoot that will change his whole life! It turns out he has a huge debt. But from where? Nobody can explain. To achieve connection, you need to submit an application through your personal account. But Zyablikov is not “friendly” with the Internet; he has an old push-button telephone. Walking in circles in the system of automatically recording fines, instructions, and personal accounts is gradually destroying it. Zyablkov himself now feels like an insect locked in a jar. And only with the rare beetle he caught can he have a heart-to-heart talk.
