Sergei, always hanging out on business trips, dreams of being on a "desert island" with his beloved Masha. A pandemic that suddenly hit the world gives him this chance by locking his lovers at home in quarantine. “In a cage,” lovers, having gone through five stages of accepting the inevitable, are forced to get to know each other anew and accept themselves and the world around as it is. And everything would be fine if not for the invasion of aliens.

In the early days of the Great Patriotic War old Kuzmich from the village of Kurakino guesses that a long war lies ahead. As the village falls under German occupation and repressions intensify, he keeps aloof, arousing suspicions. Following the execution of fellow villagers and accusations of betrayal, Kuzmich agrees to serve as a guide for the German detachment, ostensibly to get a horse and save his family. In reality, however, he is planning a sacrificial deception: through his grandson Vaska, he conveys information about the enemy's route to the Soviet troops. At the critical moment, Kuzmich leads the German mountain troopers into a trap, repeating the feat of Ivan Susanin. At the cost of his own life the old man leads the enemy to perdition, becoming a symbol of the people's resistance.
