Based on the play by Mikhail Heifets. A workshop on family psychology for a couple who have been in an “ideal” relationship for 10 years. A romantic dinner, jealousy, passion, suspicion, crazy intrigue, love, hate and just a hunger for primary feelings. But there is one question: for whom is the third device? Why exactly should there be a third? Who is he? Or is she? Become a witness to the solution of all these questions. How a couple in true love finds a way out of the game of “ideality” and returns to a sincere relationship.
