Hitler at the Opera (2014)

Aaron is an Israeli singer who comes to Poland for a guest performance in a provincial theater. The artist is warmly welcomed by the management and the theater team. During one of the rehearsals, Aaron spots backstage what he thinks looks like Adolf Hitler. Attempts are stopped and the hosts are accused of anti-Semitism. A chain of absurd situations follows, and the revealed prejudices lead to an escalation of the conflict.
