Daniel is a boy scout leader. Marie-Catherine, a haughty aristocrat. Auguste, a tormented poet. Roland, a corrupt politician. Georges, an authoritarian major. Berthe, a naive peasant. François, a collaborator. And Tayac, a not-so-clever caveman. Their common point? They are all ghosts. They live in the Château de Mérudeaux where they lead a peaceful existence, until Alison and Nabil inherit the place, arrive, and plan to turn it into a hotel. The ghosts try to haunt them to drive them away but without success. Everything changes when, after an accident, Alison can see them. Stuck in the castle due to a mortgage and ongoing renovations, she has no choice but to get to know them and discovers endearing characters who will become her new family.
