Across the globe, undercover U.S. military missions are compromised when double agents begin identifying and killing covert personnel. The situation threatens to devastate national security, so the White House calls in Mack Bolan. As the warrior flushes out traitors in Central America, the opponents manage to stay one step ahead, eventually leading Bolan to the center of Istanbul's underworld.
Posing as a spy, Bolan infiltrates the realm of black market arms dealers and intelligence brokers, determined to tear down the smoke screen and expose the true enemy of the state. Faced with an expansive operation designed to inflict harm and retribution on the U.S., the Executioner's strategy is simple and hard: strike at the heart, and don't let up until it stops beating.
