Around 2000, a group of journalists is investigating a highly secret document when they uncover a sensational story: that before the Second World War, in 1938, the first rocket was made in the USSR and Soviet scientists were planning to send an orbiter to the Moon and back.
The one who shines above the others (similar to the clear front-runners in the early historical Soviet space program) is Captain Ivan Sergeyevich Kharlamov (possibly a reference to the real-life cosmonaut Valentin Varlamov).
Most of the remainder of the film seems to follow the search for information about what happened next, as the 1930s space program appears to have dissolved immediately after, with no reason given (but presumably as a part of Stalin's purges).
A number of men are shown as suspected of being Kharlamov—the NKVD seems to be conducting a criminal investigation of the program and it is implied that those involved, including Kharlamov himself, are in hiding.
The very end of the movie shows the only footage of the mission itself after launch, explaining it as a film which was found at the landing site in Chile and is currently in the possession of the Antofagasta Natural museum.
When elements of the plot started leaking out, a number of Russian newspapers treated it as a documentary about a real 1938 event, referring to it as the Santiago Meteorite (метеорит "Сантьяго").
Fine, strong and clever heroes, then rendered [them] unnecessary to the native land – some have been destroyed, others lost in obscurity, yet others still broken by fear.
