A group of friends sets out on a holiday road trip to Greece. On their way south, they are intercepted by a group of Croatian gangsters. Locked in a remote house, they find themselves struggling for their lives.

After being employed by the Senator's wife to find the killer of their daughter, a determined detective begins an investigation in which the only evidence he finds are new waves of murders with no sign pointing to the identity of the killer.

In a world teetering on chaos, elite assassin John Rico is the go-to solution when the government wants threats removed-quietly and permanently. But when a mission goes sideways, he's given one last shot at redemption: track down and eliminate Mason Ryker, the final ghost of the feared underground unit known as The Order of the Dragon. As Rico's mission leads him to a small, danger-ridden town in Serbia, the lines between good and evil begin to blur. Is Ryker the monster he's made out to be, or is there a deeper conspiracy at play? What begins as a black-and-white hit spirals into a moral storm-and time is running out.
