ATF Special Agent Tobias Burke is undercover in West Virginia, infiltrating a militia led by Captain Dylan Connelly, suspected of murdering the Secretary of Defense. Dylan, once the Army's battalion leader of Mortuary Affairs, now works as a physician at the local Veterans Hospital, while leading her late-father's Seventh Amendment Militia. When Tobias Burke shows up to enlist, with his ladies-man humor and lovable Labrador retriever, Dylan knows his killer charm hides an ulterior motive. As evidence against Dylan mounts, Tobias's instincts-and then his heart-betray him into wondering if Dylan is being framed. Now, with Dylan's militia locked in a stand-off with the FBI and the nation watching the drama unfold on television, Tobias stares down the barrel of the most difficult choice in his life: expose the real killer and clear Dylan's name, or follow orders.
