Fedya studied at an Orthodox boarding school from first grade, and at 16, his mother transferred him to a regular school in the center of St. Petersburg. There, he meets Pasha and Tanya. Modern and energetic, they are charmed by Fedya's kindness and show him a world full of unexplored emotions, actions, and places. Fedya is completely delighted with his new life, with the possibility of teenage boundary-breaking. He falls in love with Tanya, starts coming home late, skipping classes, lying to his mother, and arguing with her, and at church he feels nothing but crushing shame. Fedya changes dramatically, both externally and internally, and the eternal values instilled in him by his Orthodox upbringing are gradually forgotten. But it is these very values that save him after a series of tragic events.
