Severely injured and left for dead in Afghanistan after a routine reconnaissance mission went disastrously wrong, Marine Sergeant Nathan Profit endured two years of unimaginable hell at the hands of his insurgent captors.

Having been subjected to never-ending psychological and physical torture, Nathan is rescued when a black-market arms dealer takes pity on his fellow countryman.

Nathan returns to the United States a very different man. Angry and hostile at losing everything in his life during his captivity, he begins to plot his revenge against the armed forces and country that abandoned him.

Putting his previous knowledge, education, and experiences to good use, Nathan becomes a firefighter paramedic.

To his friends, family, and colleagues, he is the epitome of someone who’d come through immense adversity to become a better person.

In truth, Nathan uses his emergency services role to deliver his own form of justice to the unworthy wretches created by the country he once patriotically served, and now despises.

He also plots his horrific revenge against the marines and those he deems responsible for his Afghan nightmare.

A first responder is there to save life, to help the injured and those in trouble, but if you have a questionable past or have inflicted suffering on others, Nathan Profit is the last responder you want to help you.
