On December 30, Elya is going to fly from St. Petersburg to Moscow to meet with the groom. They met on the Internet and decided to celebrate the New Year together. The groom asks her to take a case with documents, which will be handed to her at the airport. However, a young guy Denis is also very interested in the documents: he was given the task to intercept the case. He can't do it right away. In addition, due to bad weather, all flights are canceled, and as a result, Ale and Denis rent one car for two. On the way, he will repeatedly try to steal the case, but it will not be so easy. They have a long way to go, full of dangers, adventures and unexpected discoveries.
