Police officer Anna jokingly makes up a sketch of the man of her dreams. This image accidentally got into the criminal search database, and now all the district employees are sure that this is what the mysterious thief looks like, who is feared in all jewelry stores in the city. Harmless programmer Sasha, strikingly similar to Anna's fantasy, comes to the store for wedding rings for his wedding and immediately finds himself in handcuffs. The police quickly find out the truth, but decide to hide it from Sasha for the time being. Anna is assigned to keep an eye on the guy in order to catch not only a real thief, but also dangerous bandits chasing him. But it's not easy to follow a professional duty in cold blood, being around the most desirable man for days at a time.

Sasha has three problems: a girl who wants a wedding, which he cannot decide on, because he is only a veterinary paramedic and cleans the ears of dogs, parents, because mom doesn’t like Olya, and dad doesn’t like his job because Sasha cleans ears for dogs, and third - Olya's mother doesn't like him, because ... yes, because he cleans dogs' ears. On New Year's Eve, everyone gathers at Sasha's house to celebrate his birthday, because he was born on January 1. Olya has prepared a gift for him - he will soon become a dad! In order to be alone with his thoughts for a while, Sasha hides in the toilet. By pressing the flush, he finds himself ... in his parents' apartment two hours before his birth. And in the yard on December 31, 1992.
