Marc s'enfuit avec toute son équipe dans un petit village des Cévennes pour finir son film chez sa tante Denise. Sur place, sa créativité se manifeste par un million d'idées qui le plongent dans un drôle de chaos. Marc se lance alors dans l’écriture du Livre des Solutions, un guide de conseils pratiques qui pourrait bien être la solution à tous ses problèmes… Marc, a bipolar and paranoid filmmaker, cannot tolerate seeing his current project picked apart by his producers. The clips he’s been able to sneak a look at lead him to fear the worst. With his editor as an accomplice, he manages to spirit away the rushes to his aunt’s place in the Cévennes, to finish the film as he envisions it. Instead, its completion is constantly postponed, as he creates endless diversions and impasses, which alternate between the comic and the downright disturbing.
