After doing a five-year stretch in the Scrubs on a robbery charge, ex-Royal Marine Billy Robson is determined to go straight.

From the Middle East, through Britain and America, the twin evils of terrorism and narcotics stalk side by side. And Billy Robson finds himself and those he loves fighting for their very survival as he dares to stand up for what he believes in.
