After nearly losing his life in Antigua during a mission that went terribly wrong, Gideon trusts no one. But when a former lover and grifter, Arizona, resurfaces in need of his skills, she reminds him he was indebted to a man who had once saved his life: the son of the legendary con-man Scamz. Gideon is forced to take on an assignment which will lead him to Argentina in pursuit of a briefcase containing one part of a larger puzzle. The "package" contains material that another group of assassins – the Four Horsemen of the Apocalypse – will kill to obtain and protect. One of the leaders of the Four Horsemen has a connection to Gideon that neither man is aware of -- a connection that will be exposed when they meet face-to-face and gun-to-gun. Each member of The Four Horsemen is a world-class killer, each with a dark and dangerous past, and nothing will stop that team of renegades from completing their mission.
