Post Traumatic Stress Disorder In The Film Brothers

The film Brothers portrays two brothers on two completely different paths. The story of this family gives the audience an insight into the consequences of war. A very vivid example of Post Traumatic Stress Disorder is displayed. This movie is serious and I believe very relatable, especially to military personnel and families. Let me explain my findings and reasoning in the case of Brothers.
This film surrounds the lives of one family and exposes all its broken parts. One brother, Sam, "the favorite," is a Captain in the Marines headed off to Afghanistan for another tour. The other brother Tommy, just released from prison for robbery, is trying to start over on a positive path. Sam's wife Grace and two girls, Isabelle and Maggie, are heartbroken
I believe the guilt is a large reason Sam is cold and won't open up to anyone when he returns. He is quiet and isolates himself as if he isn't really present in his own life mentally. We see that Sam is angry at himself for killing a fellow soldier and he takes that anger out on others. His wife Grace and brother Tommy suffer the most projected anger and guilt when Sam accuses them of sleeping together while he was gone. At one point Sam even lashes out at his daughter for something very small. She is obviously scared of her now unfamiliar father. Sam's refusal to talk to anyone about the events he suffered or how he feels, makes it impossible for him to adjust back to normal life. It’s like pressure building and building in a soda bottle, eventual it's going to explode. Sam finally has a complete mental break when he gets his wife to confess that she did kiss his brother Tommy. Sam suddenly explodes in a fit of rage. He gets very angry and immediately starts destroying the new kitchen that Tommy had put in while he was away. Tommy arrives in the middle of Sam's fit to protect Grace and the girls. However, his presence does not help the situation. Sam gets angrier, fighting his brother and pulling a gun. When police arrive outside his house Sam turns the gun on himself. Horrified, his wife and brother try to reason with him, eventually getting him to drop the gun. The movie ends with Sam in the hospital getting the help he needs and finally opening up by telling his wife about killing another soldier. This is an obvious relief and release of bottled emotions for Sam. With his secret out Sam has taken the first step to
