A film based on the Kazakh epic poem of the XIII-XIV century. The film tells about the founders of Sarybay and Karabay, who, due to circumstances, violate the oath given to each other to seal their blood-tied friendship. However, their children Kozy Korpesh and Bayan Sulu develop mutual feelings.

Aidar and Galiya have long been in love with each other. Aidar works as a horse breeder, and Galiya is a senior herdswoman at a collective farm stud farm. One day, due to an accidental misunderstanding, the young people quarrel. Angarbay, the store manager, who is also in love with Galiya, is trying to take advantage of this.

The film takes place near the border outpost "Red Stones". Three guys: the grandson of a herdsman, his cousin, who came on vacation from the city and the daughter of the head of the frontier post, met by chance in the Kazakh border steppes, where they spent time playing games. But when the real danger comes to replace the games, the guys proved to be real border guards.

Kyz-Zhibek - Kazakh poetic folk legend of the 16th century, tells about the period in the Kazakh nation when the people suffered from bloody feuds. In those times each province of the Kazakh nation had its own Khan and each tried to supersede the other. The love story of Tolegen, the brave warrior, and the beauty Zhibek ends tragically because of inter-family strife. Tolegen is foully murdered by Bekejan (the batyr, or nobleman, of the rival family), who earlier strived for the hand of Zhibek. Zhibek commits suicide after learning about the death of Tolegen.
