Sasha has three problems: a girlfriend who wants to get married, but he can not make up his mind, since he is only a veterinary assistant and cleans the ears of dogs; secondly from parents, because mom doesn't like Olya, and dad doesn't like his job, because Sasha cleans dogs' ears, and third - Olya's mom doesn't like him, because ... yes, because he cleans the ears of dogs.
On New Years Eve, everyone gathers at Sasha's to celebrate his birthday, as he was born on January 1. Olya has prepared a present for him - he will soon become a dad! In order to be alone with his thoughts for a while, Sacha hides in the toilet. By pressing the flush, he finds himself ... in his parents' apartment two hours before his birth. And in the courtyard it is December 31, 1992.
