Lina likes and respects teenagers. She doesn't understand why grown-ups underestimate kids. This is her sincere point of view - well, maybe a bit exaggerated to gain some attention. Lina is a successful video blogger, she works at a psychology center and gets invitations on TV shows as an expert. She doesn't like it when people call her "child psychologist". One day while live streaming Lina gets a call from a weird man. He speaks in riddles, says that she does nothing but talk - a lousy psychologist who doesn't even notice what's happening right under her nose. The next day Lina finds out that her brother Dima killed himself.
