In Baghdad's Green Zone, an Iraqi scientist is murdered just before he is to reveal the monstrous secret weapon that Saddam Hussein took to his grave. The assassination is the work of a mysterious sniper called Juba, originally trained by the British but who now works with a twisted mastermind determined to wrest leadership of the Islamic terrorist world from Al Qaeda. Kyle Swanson, once the top sniper in the US Marine Corps, has become the key member in a secret operations team known as Task Force Trident. When Juba tests the new weapon by killing hundreds of people at a Britsh royal wedding in London, Swanson is assigned to hunt down his old special ops rival.
