A story based on facts. Aaron, a quiet, introverted Israeli opera singer, a star who doesn't shine so bright anymore, arrives in a little theatre in rural Poland to give a guest performance. He evokes both admiration and respect among the theatre staff. Aaron doesn't feel comfortable in the country where Jews suffered so much but, as a professional, he tries to integrate with the crew. During one of rehearsals, he feels that somebody is watching him. To his horror, the man he notices behind the curtain looks like... Adolf Hitler. When he shares his anxiety with the theatre director, she decides that the singer must have lost his mind. Aaron, however, insists that he has become a victim of a cruel joke. What follows is escalation of this absurd situation, caused by a mix of Aaron's paranoia and a certain doze of anti-Semitism, which poses a threat of starting an international scandal and might result in the premiere being cancelled.
