On New Year's Eve, 34 year old physicist and astronomer Ignat Galley flew to the capital to divorce. He was passionate about stars and worked at a mountain observatory. In Moscow, under unusual circumstances, Ignat met a mysterious girl named Taisiya Artemyeva and met her entire family: mother Yulia, sister Dusya, and clever and eccentric grandmother Yanga Lvovna. This conference has brought about a revolutionary change in the lives of astronomers. On New Year's Eve, Ignati will have to make an important decision that will not only change his life, but also his new friends.
