J’ai quitté l’Aquitaine (2006)

A filmmaker confined to a psychiatric institution tries to find healing by bringing together all the members of his family for a collective experiment: using a construction game set, they must try to recreate as precisely as possible the happiness that once filled their family home, which disappeared 25 years ago. If even one family member managed to restore everything perfectly, the patient would be cured - that much is certain. But nothing was ever going to go as planned.
