From NetFlix:

Starring Emilio Estevez (who also directed), Kathy Bates and Martin Sheen, this gripping war drama follows the battles encountered at home as a result of those on fought the battlefield. Vietnam impacted the everyday life of average American families in unimaginable ways: soldiers didn’t always return home alive, and when they did, they were often met with anger, not gratitude – even from their own families

There are several excellent films that deal with Post Traumatic Stress Disorder (PTSD). Besides this film see also two versions of the same story: Brothers (2005) and Brothers (2009).

This particular film is in some sense the most difficult of the three because of the lack of support the returning veteran gets in this case. Martin Sheen is exasperating as the father. Brace yourself.
