The Jackpot!

For twenty years, François Voisin (Thierry Lhermitte) has let his family believe he is a humdrum civil servant, when he is in fact a secret agent. His wife Hélène (Miou-Miou), bored by their routine, has begun an affair with a con artist who claims to be a spy. Claude Zidi stages it all in the Voisins' ordinary home, where François sits down to dinner holding his secret.
