Léa ,Ludovic ,Clotilde and Papillon live on swindles .They make a lotion,supposedly enhancing female beauty.Their plan is settled .First Lea goes to the pharmacies as a potential customer ,where she claims the famous liquid.It's on their catalog but,of course,not in stock.Every pharmacy orders several bottles .The foursome pockets a tidy sum after sending the magic potion,consisting of water and anything .They have more than one string to their bow:we see them swindle a diamond merchant and the poor guy has to apologize ,to boot!Then they offer 100,000 Francs to welcome a little a girl for the holidays ,but first you must pay 1000 Francs for "investigation fees" ;it's a complete success:they receive 25 ,000 answers ,that is to say 25 million .
