By an absurd coincidence, two families who did not know each other at all rented the same cottage for New Year's Eve. There is no time to give up housing, so they are forced to somehow find a common language and get along under the same roof.

Andrey Romanov finds himself at the epicenter of a clash between Russian and Western intelligence services. Together with his team of top Russian special agents, he is recruited by GRU officer Maksim Kolosov for a special mission into enemy territory. The group's goal is to find out what is happening in a secret laboratory near the border of the country, where work is underway on a new biological weapon. Andrey also has a personal goal - revenge. The enemy's team is led by his father's killer. Andrey's group is completely secret; almost no one knows about its true purpose. Everything does not go according to plan when it becomes clear that there is a "mole" among them.
