In the heart of the Muette woods in Dreux, restoration work is underway across several kilometers of ruins. The Bas Buissons site—once home to one of the largest sanatoriums in France—is now at the center of a major real estate redevelopment project.

Built in 1928 and abandoned since the 1990s, this former sanatorium still holds the stories and memories of those who worked and stayed there.

This documentary invites us to explore a unique and historic place, breathing life back into the voices and experiences that once echoed through its halls.
