Unpolished and ultra-pragmatic industrialist Jean-Jacques Castella reluctantly attends Racine's tragedy "Berenice" in order to see his niece play a bit part. He is taken with the play's strangely familiar-looking leading lady Clara Devaux. During the course of the show, Castella soon remembers that he once hired and then promptly fired the actress as an English language tutor. He immediately goes out and signs up for language lessons. Thinking that he is nothing but an ill-tempered philistine with bad taste, Clara rejects him until Castella charms her off her feet.

Because he has no choice, because he is in love with his wife and because he refuses to resign himself to the worst, Samuel Polaris decides to regain his dignity. Even if, to do this, he has to steal from his psychiatrist the watch that Kennedy was wearing the day he was assassinated.
