It is time for thirty-something Ludovic Chambercy to succeed his father Jacques at the head of the family business: the Chambercy Galleries. But faced with his new duties, Ludovic begins to sweat, has panic attacks and even dizzy spells. He is diagnosed with hypegiaphobia or extreme fear of responsibility. This man with everything for a happy life seems to be shying away from the expectations of his family. Reluctantly, without a word to his father and girlfriend, Ludovic starts group behavior therapy. While his lies spark off an incredible series of tragicomic events, Ludovic strikes up a friendship with the other phobics in his group: Léon, trader in bric-a-brac, who can no longer stand untidiness; Clémence, a student who cannot bear even one second of her own company and Margaux, who can no longer touch or be touched. And if Ludovic is to find a cure at the end of the road, there will be a few surprises in store for him along the way...
