An inn in the countryside. Close friends from their school days have gathered here: the investigating judge Sergei Zemtsov (Alexei Serebryakov), the doctor Alexander Pirogov (Sergei Vexler), the wealthy landlady Liudmila (Iana Nikolaeva), the businesswoman and simply a tycoon of the Economy Irina Goncharova (Oksana Fandera), the drunkard-slacker Fedia Belkin (Andrei Tashkov) and the actor-TV star Andrei Viechny (Igor Yatzko). All these people of different professions and lifestyles are gathered to celebrate a simple date: the 15th anniversary of the last day of their schooling. Since all the rooms in the inn are occupied, the friends have retreated to the comfortable hunting lodge made available to them nearby by the provident Irina who had rented it. According to her story, the very dangerous bear Shatun roams around, who has already devoured a man. Irina had arrived with her guard, Lieutenant Kuroi (Alexander Tsurkan) to free people from the fear of going out into the street. They organize a noisy party, everyone has fun, remembering the good old days!
But suddenly next to the house, in the middle of the party, the most dangerous bear appears: Shatun. A shot rings out. Death of the dangerous animal. But in the skin of the dead bear, the friends found one of the guests at the table, the cheerful actor, who had decided to play a prank on his friends. The failed joke turned into murder and the danger came not from the bear but from the past of our heroes. Was the shot fired by chance? Who fired? Obviously something terrible is hidden under the appearance of a friendship of former students.
