 François is a middle-aged antique dealer. He has a stylish apartment and a fabulous life, but at a dinner with a group he considers his dearest acquaintances, he is blindsided by the revelation that none of them actually likes him. He s arrogant, self-centered and harsh, and they don t believe he knows the meaning of friendship. His business partner Catherine makes him a bet: if he can produce his best friend, she will let him keep the massive Greek vase he acquired that afternoon on the company tab. If not, it s hers.  Having accepted the wager, François naively tears through his address book, trying to shoehorn an increasingly unlikely series of contacts into the all-important role. Moving through Paris, he keeps encountering a trivia-spouting, big-hearted cabbie named Bruno. Bruno s chatty, lowbrow ways grate against François s designer temperament, but he covets the other man s easy way with people. He convinces Bruno to teach him how to make friends and sets about learning the "three S s" - being sociable, smiling and sincere - though they don t come easy. Ultimately, François victory will depend on Bruno s naiveté in playing along, but what s the cost of cheating at friendship?
