Skilled in the art of murder, an organized-crime group, known as the Elements of Death, is planning an assassination to place their own man in a powerful position. Their number has come up on Mack Bolan's hit list, but the killers are prepared to fight back with all they've got and that includes a mole inside the Justice Department. Chicago becomes a battleground between the Executioner and a gang of the most ruthless hired guns in the world. When Bolan takes out a key female Elements leader, it's up to a skilled lady Fed to impersonate the fallen assassin and create enough heat to force the enemy into Bolan's gun sights. And when it comes to those who earn their living selling death, the Executioner demands nothing less than blood for blood.
