When Navy SEAL Mack Bedford’s fellow officers are brutally killed by Iraqi insurgents using a cruel, new, anti-tank Diamondhead missile, Mack avenges their murders by gunning down the then-unarmed attackers, ultimately getting himself court-martialed and kicked out of the Navy in the process. To make matters worse, Mack then learns that the Diamondhead missiles were sold illegally by French industrialist and infamous politician Henri Foche. Mack suspects that Foche will succeed in his campaign to become the next French president and fears that his election will promote the spread of international terrorism.

In addition, Mack has a gravely ill son whose life can only be saved with an experimental and unaffordable foreign medical procedure. So when Mack is asked to help assassinate Henri Foche, he finds himself agreeing. His reward: a chance at survival for both his son and the country.

But before Mack can reach Foche, a jilted mercenary group warns the Frenchman of the threat, greatly increasing the difficulty of Mack’s solo assassination attempt. Can Mack track down and murder the French tyrant as he has been commissioned to do? Does he have the power to restore his reputation as a Navy SEAL? And will he be able to save his son before it’s too late?
