Fifty years after the fall of the Berlin wall, walls continue to exist. Visible and invisible walls, those of prejudice, which are the most difficult to break down because they live inside of us. WALLS is the story of men and women who spend the night at Nogales along the border that divides USA from Mexico. On the other side there's the Border Patrol, Sheriff Joe Arpaio in Phoenix, a group of patriots and 'the Samaritans'. In another part of the world in Mitrovica in Kosovo, the stories and the old ethnic and religious hatreds of the Kosovan Albanians majority and the Serbian minority are facing and alternating around a bridge that divides the city into two like a wall.
