François is a dealer in antiques, a man completely immersed in his trade. On the occasion of his birthday, his associate Catherine candidly infoms him that he has no friends. The other guests agree: François’ passion is confined to the objects he buys and sells; he cannot connect emotionally. François is shocked - surely they're joking? He has nothing but friends, his days are full of meetings, of people. But Catherine insists: she's talking about friendship, not business. François insists - she's talking nonsense. When things get really heated between them, Catherine offers achallenge: François must produce one of these good friends, a real friend - his best friend. He's got ten days to find him.
