Aldo becomes his boldness coach. Pierre gets a job washing dishes where Agnes is staying, but after a week or so, she's off to Deauville, with Aldo and Pierre in pursuit. Using funds they get by selling Aldo's car, this time Pierre poses as a polo-playing jet setter. Will this win the heart of Agnes?
