Residents of a big city, each of whom has their own sexual problems and desires, secret and, most often, shameful from the point of view of society, need to solve them. Each of the characters tries to solve their problems in their own way: someone sublimates them, someone turns to a psychotherapist for help, someone rushes into experiments... but sooner or later they all return to where they started, and they have to overcome themselves again and again to get at least a little, even a millimeter closer to their happiness.

The action takes place shortly after the end of the Second World War in the Siberian hinterland, among Russians and Germans with damaged personal stories and a strange transformation: the victors seem to be crawling into the skins of the defeated, and vice versa. Ignat, is the embodiment of the larger-than-life image of the Soviet victorious warrior who, in fact, proves to be shell-shocked, sick and broken, although not completely destroyed. Trains become fetish for the heroes of the film, and speed becomes a mania; they virtually become one with their steam engines, while the machines take on human names. The heroes set up an almost fatal race in the Siberian forest, risking their own lives and those of others.

In a reality created by the Architect, events unfold which follow their own logic. However, everything changes when the Architect becomes a participant of the events. Now the Architect is in danger, and there is only one way to be saved, to control his own thoughts.
