Long ago, the condition was called "shell shock," but the psychological affliction faced by many combat veterans now goes by the less violent─but no less serious─name of post-traumatic stress disorder. This revealing documentary reviews the history of PTSD, focusing on soldiers' own writings as well as combat scenes and first-person interviews with vets and families from World War II, Vietnam, Desert Storm, and the Iraq War. 68 min. Widescreen (Enhanced); Soundtracks: English Dolby Digital stereo, Spanish Dolby Digital stereo; bonus footage.
