High in the mountains of the Trans-Ili Alatau there is an experimental station of the Kazakh Institute of Animal Husbandry. A young scientist, Jacques Dosanov (Shaken Aimanov), is working on breeding a new breed of sheep, trying to cross a merino sheep and a wild argali ram. With great difficulty, he manages to catch argali in the mountains. Datsanov and his assistant Saule take care of five sheep fertilized by a wild ram. But in difficult mountain conditions, four queens died, and the only lamb born from the fifth sheep was killed by an accidental shot by a hunter. However, Hasanov does not give up. He undertakes to repeat his experience, this time on an immeasurably large scale. A few years later, the scientist managed to grow a whole flock of archaromerinos.
