A young widow wants to carry on with her husband's work:managing a pine plantation where they extract resin;but most of all,she wants to have electricity installed in her valuable property.In this place,it seems that 1789 never happened and that time stood still:her workers,circa 1920,do not receive any salary and ,like the peasants in the middle ages,have to bring their production to their landlady. But her progressive ideas come up against men still remembering WW1 and against her bourgeois peers.Her foreman ,first bewildered ,is finally won over by his boss' resilience and strength of character.For her own good,the young heiress is too ahead of her time though.
