A documentary film shedding light on some pages of our space history, telling about the fate of its unknown protagonists, academician Vladimir Ponomarenko, pop artist John Gridunov, doctor-researcher Alik Mnatsakanyan. The film is based on unique video materials filmed during secret experiments with living people, conducted at the Institute of Aviation and Space Medicine, as well as on modern filming material that tells how they live, what they remember, what they think, what veteran space testers dream of today.

The film is dedicated not only to the history of the creation, formation and creation in the current, practically “childless” cinema of a unique children's film magazine. It also tells about adult directors, actors, playwrights, composers, artists and cinematographers, as well as people of other cinematic professions who have seriously and lovingly worked on funny children's stories. And about the children who have grown up with Yeralash. And, despite the fact that not all of them went to the "artists", they continue to be faithful to him.
