Other Side of Zero is an intimate portrait of the lives of three men who were a part of the construction crews responsible for the clean up of Ground Zero after 9/11. With unique access to these men and their families, first time director Chris Hillman documents the devastating effects post traumatic stress disorder (PTSD) has on the lives of those suffering from it. In true documentary style this raw film gives us a glimpse into an untold story of 9/11. Gregers Sall, the award winning editor of the documentary film 'Senna,' is the film's editor.
