Mince alors !

Nina, an outgoing, energetic young woman, is the financial director of a swimwear company. When she gains a few pounds, her husband Gaspard, who's the director of the company, reproaches her for her weight gain. He advises her to go on a one-month retreat at Brides-les-Bains, a spa resort in Savoie known for its weight-loss program. To avoid making waves, Nina puts her pride aside and travels to the spa.

Soon after arriving, she makes friends with Sophie, a lawyer from Marseilles who's as thin as a twig and Emily, a mother who wants to lose 50 pounds and gain a little self-esteem. Between dietary meals, massages and gym sessions, the three women discover that friendship can be a formidable ally.
