Deep cover agent Martin Odum returns to the FBI after an assignment infiltrating the Citizen's Army of Virginia, a domestic terrorist organization. He tries to re-connect with his estranged wife and son, put his life back together and get the last "legend" behind him but when the CAV announces an eminent attack, Martin must go back under in order to stop them. Also, a mysterious stranger confronts Martin to tell him that his whole life may be a deep cover legend and that everything he thinks he knows is a lie.

Martin assumes the legend of Dante Auerbach, an international arms dealer known as the "Lord of War," in order to track the sale of VX gas and rescue kidnapped chemist Richard Hubbard. He makes contact with beautiful arms dealer Ana Paulanos, the right hand of a mysterious Chechen mobster known as "The Colonel." Martin develops a romantic entanglement with Ana as he gains The Colonel's trust - but it's unclear whether he trusts him enough to trade him all the VX gas.
