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.

Martin is put on leave after the confrontation with The Colonel. He begins looking into his own past and The Stranger's assertion that "Martin Odum" is a legend. This off-book investigation leads him to a mysterious smuggler in Houston named Kyle Dobson, who may have the answers he needs. Martin assumes the legend of a Southern outlaw named Len Barlow in order to infiltrate the smuggling operation and get close to Dobson.
