veterans' families

Beginning with the first documented cases from the Civil War, the film examines occurrences of PTSD through two World Wars and Vietnam, as well as more recent cases involving soldiers who served in Iraq and Afghanistan. The stories are told through soldiers' revealing letters and journals; photographs and combat footage; first-person interviews with veterans of WWII, the Vietnam War, Operation Desert Storm, and Operation Iraqi Freedom; and interviews with family members of soldiers with PTSD.

Centering around the burial of the Unknown Warrior in Great Britain in 1920, the story follows the lives of three women, Hettie, who is attracted to a man with hidden troubles, Evelyn, who is dealing with her brother who has not been the same after the war, and Ada, who meets a young veteran who knew her dead son.
