Wherever the president of the United States goes, four perimeters of protection surround him. The fourth and final perimeter is a nearly impenetrable ring of agents, the commander-in-chief's literal bodyguards.
Kurt Ford is a former Secret Service agent who has become a successful high-tech entrepreneur. A widower with one child, his proudest achievement is his son, Collin, a young Secret Service agent assigned to guard the US president. But on a foggy night in Georgetown, Collin's body is found in his apartment and the police rule the death a suicide. Devastated, Ford knows his son would never have taken his own life, and he becomes suspicious when he discovers that several other young agents have also died, presumably because they all had witnessed a strange, secret meeting, involving the president, at a remote Maryland farmhouse.
Ford becomes obsessed with finding the truth. Shockingly, the trail of evidence leads to none other than the president of the United States. Although Kurt Ford is a man at the pinnacle of power and on the verge of a new marriage, he plots to do the unthinkable-assassinate the president. But when he sets his plan in motion, he quickly discovers how much he really has to lose-and what dark forces are waiting for him to make his next move.
