Kevin McCann is the alias of Radford Hayes, a former black-ops agent who assumed the identity of Kevin McCann, a soldier in his unit, and took work as a cabbie in order to hide the fact that he was making a dirty bomb. He recruits his fellow soldiers, Evan Bauer and Jack Cochran, to help make the bomb and plant it in a US city in order to simulate a terrorist attack and stir up anti-terrorist sentiment again.
