Sliding doors open and close automatically, exit to the left, entrance to the right. Beyond it, cars go by, and pedestrians and cyclists. A large park behaves as if nothing has happened. The mirage of a world intact. In an instant, a life changes forever. After he falls from a scaffold on the construction site where he works, the comatose David is visited daily by his wife, Caroline, and their six-year-old son Bertrand - but despite their devoted efforts, there's no crossing the ineffable divide between consciousness and the mysterious world David now inhabits.
