Facility No. 6, a juvenile protective detention center, stands on the verge of closure. A documentary crew steps inside to record what little remains, and from the moment the cameras turn on, they find themselves before long-buried wounds and truths no one has wanted to face. In the worn faces of teachers who have spent themselves caring for these children, and beneath the indifference of a society that has long since turned its head away from the other side of the wall, the crew quietly bears witness to how children with nowhere left to go have arrived at this place.
