The film is about a young trumpeter Nicholas Shevchenko. He's a talented musician, who also writes his own music, attracting the attention of the world famous musician Eugene Gaisin, who tours the city.

The kidnapper gets into the house where the nine-year-old girl Nadya and her animator, student Lenya, are left. His target is a girl. The student will have to make a choice: resist and risk his life, or allow the girl to be taken to save himself.

Instead of a pleasant getaway in a rented country house, four women — a grandmother, a mother, a 15-year-old granddaughter, and an elderly housekeeper — are faced with a night full of doubts and suspicions after suddenly discovering the body of a man in one of the rooms on the ground floor. Is it a corpse or not? That’s the question! And will one of them have to take the blame for something none of them actually did? The closer it gets to morning, the more unexpected the twist — almost like in one of those foreign detective films they watched on TV the night before.
