Arman, Arsen, and Askhat have been competing with each other since childhood—over everything from toys to their parents' attention. Over time, nothing has changed. Every year, when they return to their hometown to celebrate their father Duman’s birthday, they resume their rivalry, boasting about their achievements and trying to one-up each other. Askhat sincerely hopes that this time will be different, and even promises his wife Saule that he won’t react to his brothers’ jabs. However, his hopes are dashed when Arman and Arsen drag him into yet another battle for the title of “Best Son.”
The father of the family, Nursultan Kopzhasarovich, respected in society, owns the entire farm in the village, so his only son Bolat grows up careless and spoiled, which more than once leads to problems and even criminal liability. At another drinking party, Bolat rapes a local school graduate. The father wanted to hush up the matter again, but the girl’s parents had already filed a statement with the police. The only way out of this situation is a wedding, but the life of the family turns into a real nightmare.
