Pierre Brochant (Thierry Lhermitte), a famous Parisian publisher, attends a weekly “idiots’ dinner”, where guests, who are prominent Parisian businessmen, must bring along an “idiot” of whom the other invitees can make fun. At the end of the dinner, the evening’s champion idiot is selected.
Pierre Brochant manages, with the help of an “idiot scout”, to find a “gem”: François Pignon, a Finance Ministry employee who is crazy about building replicas with matchsticks. Things start to go haywire when Brochant’s wife leaves him shortly before François Pignon arrives at his apartment. When Pignon arrives, he tries to help Brochant, but makes many bad mistakes. Eventually, he brings in his friend, a tax auditor, who makes an unpleasant discovery about his own wife.
