在这部外亲戚米哈伊奇喜剧片中,别利亚科夫一家充满了误解：一家之主弗拉基米尔忙于生意，妻子奥克萨娜忙于社交。而儿子马克对这一切都不感兴趣，他更忙于为流媒体频道拍摄视频。当一家之主的表弟米哈里奇出现在家门口时，一家人的平静变得更加岌岌可危。米哈伊奇也有自己的头疼事：莫斯科人正在夺走他家乡的森林，所以这个粗犷的俄罗斯男人来到首都，想把问题消灭在萌芽状态。在这个过程中，他可以和亲戚住在一起。这个粗犷的西伯利亚人潇洒地融入了别利亚科夫一家：他成了马克的朋友，马克认为他是一个潜在的怪胎博客写手；他成了哥哥的麻烦，哥哥天真地以为米哈伊尔奇会钦佩他亲戚的成功。与米哈伊奇相处并不容易，但是......共同的问题只会让别利亚科夫一家更加亲密。
Total misunderstanding reigns in the Belyakov family: the head of the family, Vladimir, is busy with business, his wife Oksana is engaged in secular affairs. And son Mark is not interested in all this, he is much more interested in shooting videos for a streaming channel. The calmness of the family becomes even more precarious when the cousin of the head of the family, Mikhalych, appears on the threshold of the house.
