In the unforgiving countryside of eastern Afghanistan, Private First Class Tyson York is thrust into a situation with improbable odds of survival where he learns the difficult lessons of loss, unshakable loyalty and love. Tyson, who is deployed to an active theater of war for the first time, is initially appalled at the casual way that his fellow soldiers discuss the deaths of their enemies and he vows to retain his decency as a human being. But when he is injured and witnesses the true horrors of combat, unbelievable boredom between missions and experiences betrayal from the home front, he finds himself enthusiastically wishing for the destruction of his enemies. After he returns from the war, Tyson realizes that he's changed and seeks help to cope with his altered emotional state. Over time, and with the help of a beautiful young woman, he learns how to cope with his PTSD and overcome the adversity that he faces upon his return.
