In a small town in the North of France, a region that was the flagship of the mining industry for many years, young and old alike are struggling to find work. While several former workers decide to hold a siege in front of a disused coal mine that is to be dismantled, two long-term unemployed men, Di Lello, whose wife runs the household, and Arnaud, a divorced man who has to take care of his sick mother, have the excellent idea of building an "artisanal" amusement park. By saving the mine and its memory, they will regain strength and dignity.
