Desperate to make the world more beautiful in a legitimate way, a young wayward engineer Artyom decided to rob several luxury apartments with the help of his invention. But in the first of them, he meets a cunning girl, Stefania, who demands to take her as an accomplice in order to buy a gift for her mother. They have only one New Year's Eve to pull off the case, and a lot of unforeseen circumstances.

Stefaniua discovers her talent as an actress. In parallel with filming, she runs a popular blog. It especially attracts the attention of several young fans - Aleks, who dreams of becoming a star, the withdrawn excellent student Masha, the technical genius Tima and the enterprising Vanya. When one of the filming days, the main character of the film in which Stefaniya is filming - Gennadiy the pony - is kidnapped, and the stunt cowboys lose sight of the kidnappers, the girl decides to take matters into her own hands and turns to her subscribers for help. Now Masha, Tima, Aleks and Vanya have to team up to find the pony and finish filming the New Year's hit.

It's New Year's Eve. Stefania and her friends are busily preparing for the holiday. However, Stefania's mind is elsewhere: she failed the audition for a popular musical, and her dream is to become a professional singer. Suddenly, thieves break into Stefania's apartment to steal the diamonds she recently found. Now the friends must embark on another journey to save their friend from trouble.
