A family with five sons lives in a remote Kazakh village. In accordance with the Eastern tradition, the eldest son, 13-year-old Aslan, becomes the Father’s deputy, in charge of all the work, and delegating the tasks. One day Aslan takes his brothers to the river for a swim - a moment of deep happiness. From then on, life is different. And when Kanat, an unknown cousin, unexpectedly arrives at the village, the structured life of the family begins to fall apart for good.
