Victor Pivert (Louis de Funes) is a very tolerant man, provided you are white, Catholic, and French. To everyone else, he is a shameless racist, who believes foreigners should go back where they came from. On his way to his daughter's wedding, Victor uncovers a group of scheming Arab revolutionaries. After Victor is discovered, he hides himself by dressing up as a rabbi, leading to one madcap scene after another.
