As a child, on the eve of March 8, Vitya was hit on the head by a swing and miraculously survived. Since then, three of his friends celebrate this date every year as their friend's second birthday. But this time, the fun goes too far. The guys wives and girlfriends will have to save them from problems and the consequences of a protracted party.
Autumn 1929. Lina, from the noble Golitsyn family, arrives on a date with her husband Georgy Osorgin, who is serving a prison sentence in the Solovetsky special purpose camp. Lina does not know that after she leaves the island, her husband will be shot. Osorgin received a terrible sentence after he, a deeply religious man, secretly brought holy gifts to the dying Archimandrite so that he could take communion before his death. The camp authorities took the Russian officer's word of honor from Osorgin not to tell his wife anything about his predetermined fate. Only on this condition did they agree to temporarily release him from the punishment cell for his last meeting with Lina. The spouses spend the precious three days allotted to them and feel happy in the most inappropriate circumstances. Osorgin says goodbye to Lina on the pier. When the ship becomes a dot on the horizon, the guards escort George back to the punishment cell, where he carefully dresses for his final journey.
