This film was made on a real criminal case. It happened in a provincial town. There were apartments in one stairwell where the family lived. And there was a single man living in the next apartment. He had recently returned from prison and was drinking heavily. The father of the family also drank heavily. So that they with neighbor as they say found each other. One afternoon all the adults were at work. At home there was only one Irina-a schoolgirl, a student of the 8th grade. The neighbor was already drunk, he decided to go to the girl's father to drink a bottle of vodka together... The drunken brute wanted to rape the girl. But he didn't succeed. His years in prison had not improved his potency. And the girl shouted that she would complain to the police... The drunk bastard fell asleep right next to the corpse. On all questions-WHY YOU DID IT, he neither during the investigation nor in court could not answer anything.
