Amir and Dima are connected not only by their work on the radio and a rented apartment for two in Almaty — they are brothers. My father died a long time ago, and my mother, Maryam, lived in Karaganda. The guys' lives went on as usual — work, home, attempts to realize themselves in their business and arrange a personal life. Mom periodically came to visit the children, but on one of these visits everything changed. Without telling her sons the real reason for her arrival, Mariam secretly went to the cardiology center.
