The Oscar-nominated Hell and Back Again makes its debut on PBS's Independent Lens. Embedded with the Marines in Afghanistan in 2009, photojournalist and filmmaker Danfung Dennis captures the frontline action experienced by Echo Company. He then follows one of the injured, Sergeant Nathan Harris, back home to North Carolina to chronicle his recovery. Dennis masterfully contrasts Harris' two worlds, demonstrating how returning home can be as traumatic as the war zone itself. Check local listings.
