Vovik and Yulia had an ultrasound scan. In order not to upset his Aunt, Julia lies that he will have a grandson. Gradually, the whole family becomes involved in this intrigue. Everyone has their own reasons for deceiving their Father-in-law.

Vovik does not want to celebrate the New Year with Julia's parents, they just stopped by to congratulate. Lena and Pasha also find themselves there. My father-in-law still hasn't bought a Christmas tree. His mother-in-law sends him to get the tree. The father-in-law takes the sons-in-law with him to help.

While the Father-in-law and Mother-in-law are on vacation in Thailand, Lena dragged Pasha to her parents' apartment to pick up her old children's things. But Julia and Vovik are already there. While the sisters are sharing things, the parents are returning from vacation. A week earlier. And there is a reason for this.
