From the warehouse manager of the Soviet farm, Bigai, he learns that Jangir is the son of the murderer of Ramazan's father and informs Amzat and Ramazan of this. The old man demands a blood test. Ramazan makes a decision, but when he meets face to face, he refuses his intention. Then Amzat asks Mirza to kill Jangir. Ajar, who loves Ramazan, tries to warn him. Mirza runs into the girl and arrests her. Ramazan and Jangir come to the rescue and capture Mirza. The wounded Ajar is taken to the hospital.
