Mac Callahan has left the fast lane of the FBI, trading a firearm for tea parties with his baby girl, and dangerous raids for a game of catch with his son. Still, he is restless. When the North Star Gala, a charitable affair his wife Samantha has been planning, unexpectedly finds its way to his home in Shadeland, Alabama, he's asked to oversee security for the event filled with Washington insiders, politicians and the elite. The U.S. President and Secretary of State are coming to Lone Oak. Finding his way back to Washington, D.C. to lead the project, he's met head on with his former life as a free-wheeling bachelor and his long-time assistant, Micah. But when Micah's sister goes missing from a college field trip, Mac walks away from the Secret Service and their plans, taking the opportunity to quench his thirst for action and the lead to find the young girl. Expecting an open and shut case, what he discovers is far worse than he could've imagined. Deep in the darkest part of the Internet, a human trafficking ring operates so steeped in anonymity, its patrons are highly protected--all the way to Capitol Hill.
