Serge is one of the best kitchen salesmen in France. For the past 30 years he’s been operating in shopping areas and department stores, securing his employers an immediate, spectacular return on investment.

When Gérald reaches out to him to help him get a job so that he can fund the renovation of his future restaurant, Serge gives it some thought before getting him hired as a salesman. Against all odds, Gérald finds out he has a gift.
