A small African nation comes under siege when its president and his cabinet are kidnapped by a band of ruthless guns for hire. Their leader is a glory-seeking, modern day Teutonic warrior who yields a machine pistol instead of a sword. The Desert Knights cut a grisly path of slaughter through city streets and swirling sands, forcing the U.S. to take an arm's-length approach by sending in Mack Bolan. With freedom and justice hanging in the balance, the arm becomes a hammer as the Executioner escorts the Desert Knights on a brief tour of hell.
