The United States' top assassin Brady Hawk returns to attack a covert operation that's funding the terrorist group Al Hasib. Deep in the jungles of Sierra Leone, Sefadu Holdings is making a mint by funneling diamonds to Al Hasib in order to fund its terrorist operation. However, when the secret black ops group Firestorm learns about it, Hawk is dispatched to squash the illegal dealings. While Hawk is battling nefarious forces abroad, his handler Alex Duncan is dealing with her own issues, including making sure that Firestorm director J.D. Blunt is safe from an attack on his life. As Hawk goes deep under cover, he must figure out a way to stop Al Hasib from getting the diamonds while Duncan fights for her life and the black ops program she believes in. But when everything starts to unravel, Hawk must find a way to keep it together on both continents or risk losing everything.
