A bygone symbol of the luxury of yesteryear and a true institution in a provincial town, the "Grand Magasin" is living its last hours. Indeed, the management, which can no longer afford the establishment, is preparing to sell the store to a large distribution group. Agathe, a saleswoman in the men's department for more than 25 years, is shocked to discover that all the staff will be laid off. Feeling both betrayed and responsible for the future of the "Grand Magasin", she becomes a passionaria, leading her colleagues to revolt, a true leader. The operation finally seems to bear fruit when the sale is cancelled and a new director is appointed.
