The Grande Raccordo Anulare (GRA) is the ring-road highway that encircles Rome. More than just a road, the GRA traverses an area of constant turmoil. Gianfranco Rosi spent two years exploring the road in a minivan, discovering the invisible worlds and possible futures harbored in this area. In this reflective and often humorous documentary, elusive characters and fleeting apparitions emerge from the background of this winding road. Directed by Gianfranco Rosi. Produced by Marco Visalberghi.
