Dallas, 1963: Dan Wilson is a Dallas PD detective with something to hide. He’s secretly helping Bobby Kennedy’s FBI investigate police corruption between Captain Eastbrook and the Dallas mob. But Wilson isn’t doing it out of the goodness of his heart. He’s got his sights set on Washington and becoming an FBI man.

Officer JD Tippit is Wilson’s ex-partner. He has bills to pay, troubles at home and a career that’s going nowhere fast. He has nothing to lose when he agrees to help Wilson dig up dirt on the department’s top brass. They catch a break when they find a scared young man caught up in the Dallas underworld. His name is Lee Oswald.

Officer Harry Denton never met a corner he couldn’t cut. A proud member of Captain Eastbrook’s cadre of crooked cops, he’ll do anything to protect his boss and keep the river of dirty money flowing through the department.

Wilson, Tippit and Denton soon lose their way in a shadow world of mob bosses, bigots, bureaucrats and power brokers named Ruby, Marcello, Walker, Hoover and Kennedy. In a sweeping saga that spans the seedy strip joints of Dallas to the halls of power in Washington, these three cops are on a collision course with history. And not all of them will make it out alive.
