Sébastien Chantoux, (
Lucas Belvaux), a psychoanalyst, leaves Paris and goes to live in the
Creuse, at
Royère-de-Vassivière. Hardly settled, he discovers "Troc'En Creuse", a system of local exchange that operates through the use of
barter. Initially reticent about using it and bartering his psychoanalytic sessions, he is reconciled to the system, and in a few weeks becomes a figure in the community. Everything seems to be working out, and without costing Sébastien a sou, until the arrival of Mlle. Oudinot, (
Catherine Mouchet), a tax inspector. War is declared; "Troc'En Creuse" and the small local economy against the capitalism of the state. == Cast ==
