Overview: Gérard Depardieu and Laurent Audiot visit places in the Paris region that are home to products that are sometimes little known: the roof of the Paris Opera House and its beehives, Méréville, the capital of watercress, Milly-la-Forêt and its mint, Saint-Ouen-l'Aumône and its old mushroom beds... The two companions then take a break in a Parisian bistro before going to observe the making of (real) Paris ham. The journey ends in the vegetable garden of the castle of Courances.
