Season 1

A deep-cover operative named Martin Odum, who has an uncanny ability to transform himself into a different person for each job. But his own identity comes into question when a mysterious stranger suggests that Martin isn't who he thinks he is.

Martin, Crystal and Troy Buchannan go undercover when a chemistry teacher and his family are kidnapped. The case takes on urgency when it's feared the kidnappers will use the teacher to manufacture a deadly gas.

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 does he trust him enough to trade him all the VX gas?

Martin is sold VX gas, resulting in the apprehension of the Colonel and Ana Paulanos. In response, one of the Colonel's minions releases VX on a crowded bus, and promises more attacks if the Colonel and Ana aren't released.

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.

Dobson's mysterious employers, The Verax Corporation, send a team of professional hitmen to retrieve Dobson, forcing Martin to take his prisoner on the run in a frantic escape back to Los Angeles.
