Frankie Armstrong’s wife’s rejection, hit him like a sledgehammer. Desperate, depressed, and suicidal, the former British soldier gets just the distraction he needs when the American, who saved his life in Iraq, calls in a favor and asks Frankie to come to Florida to find his missing nephew.

Shortly after arriving on Florida’s sun-soaked coast, what was said to be a simple search and rescue becomes something else entirely.

Joined by an adopted stray dog, Frankie races to stay ahead of the game but then discovers his old pal who asked for his help, left out a million-dollar detail. Has he been double-crossed and will repaying an old debt cost him his life?
