France Boutique (movie, 2003)

Francois Cluzet and Karin Viard are the couple behind a French shopping channel whose business and marriage are both drifting towards the rocks, with Nathalie Baye as a smiling Rottweiller out to steal their business by conning them into offering a duff product, the 'Fear Eliminator,' and picking up the network for pennies in the ensuing financial fallout.
