On the outskirts of Moscow, in a grim, sparsely populated house-tower, a motley group gathers in the late evening in an ordinary apartment. Among them are a housewife, a psychologist, a secretary, and a prostitute. They came for a psychotherapeutic session to solve their own problems, get rid of fears, complexes, and painful memories. But instead, they became hostages to someone else’s evil will.
Does any of them have a chance to escape this “island of evil,” or are they all doomed? After the death of the first victim, the gathered group begins its own investigation. But they must hurry, while the maniac hasn’t dealt with them one by one. But who is he? Maybe the one who shouts the loudest for the destruction of the madman?
