July 4th weekend, New York City: As thousands of holiday travelers make their way out of Manhattan, a flawlessly executed terrorist attack plunges the city into a maelstrom of panic and death. Amid the chaos, an elite team of foreign operatives is systematically searching for one of their own, a man so powerful that the US government refuses to admit he even exists and will do anything to keep him hidden.

Buried within the black ops budgets of the Department of Defense, a new spy agency has been created. Unfettered by the oversight of self-serving politicians, it reports only to a secret panel of military insiders. Its job is to target Americas enemies - both foreign and domestic - under a charter of three simple words: Find, Fix, and Finish.

September 1789: U.S. minister to France Thomas Jefferson, charged with forging a truce with the violent Muslim pirates of the Barbary Coast, makes a shocking discovery - one that could forever impact the world's relationship with Islam.

Every politician has a secret. And when the daughter of a politically connected family is kidnapped abroad, America's new president will agree to anything - even a deadly and ill-advised rescue plan - in order to keep his secret hidden.

Born in shadow and kept from heads of state, there are some missions so deadly, so sensitive, that they simply don't exist. so deadly, so sensitive, that they simply don't exist. When one such mission goes horribly wrong, a wave of dramatic terrorist attacks is set in motion. Their goal: the complete and total collapse of the United States. With the CIA's intelligence abilities hobbled, former Navy SEAL Team 6 member turned covert counterterrorism operative Scot Harvath launches an audacious plan to infiltrate the terrorists' network and prevent one of the biggest threats the U.S. has ever faced.

Somewhere, deep inside the United States government, is a deadly list. Members of Congress never get to see it and only the president has the final say over it. Once your name is on the list, it doesn't come off - until you're dead. Someone has just added counterterrorism operative Scot Harvath's name to the list. Somehow, Harvath must evade the teams dispatched to kill him long enough to untangle who has framed him and why they want him out of the way.

When a mysterious new weapon tips the balance against American and allied forces throughout the Middle East, the only person the president can call for help is the man the administration has just fired - Navy SEAL turned covert Homeland Security operative, Scot Harvath. Caught live on Al Jazeera in an off-the-books operation, Harvath is forced to go to ground, as a senator with presidential aspirations turns her sights on the White House and forces President Jack Rutledge to publicly end the career of America's number-one counter-terrorism operative.

Hidden deep within one of the world’s most powerful organizations is a secret committee with a devastating agenda. Its members are afforded incredible protections—considered elites, untouchables. But when four seconds of video is captured halfway around the world and anonymously transmitted to DC, covert wheels are set in motion, and counterterrorism operative Scot Harvath is tapped to undertake the deadliest assignment of his career.

After a CIA agent mysteriously dies overseas, his top asset surfaces with a startling and terrifying claim. There’s just one problem - no one knows if she can be trusted. But when six exchange students go missing, two airplane passengers trade places, and one political-asylum seeker is arrested, a deadly chain of events is set in motion.

The most unlikely terrorist enemy of all now holds a knife against the country’s throat. With both diplomatic and conventional military options swept from the table, the president calls upon Navy SEAL turned Secret Service agent Scot Harvath to disable a brilliantly orchestrated conspiracy intended to bring the United States to its knees. Teamed with beautiful Russian Intelligence agent Alexandra Ivanova and a highly trained CIA paramilitary detachment, Harvath embarks on an adrenaline-fueled search that spans the world.

The world’s largest bounty has just been placed upon America’s top spy. His only hope for survival is to outwit, outrun, and outlast his enemies long enough to get to the truth. But for Scot Harvath to accomplish his most dangerous mission ever - one that has already claimed the lives of the people closest to him, including his new wife - he’s going to need help - a lot of it. Not knowing whom he can trust, Harvath finds an unlikely ally in Norwegian intelligence operative Sølvi Kolstad.

After rescuing the President from kidnappers, Navy SEAL turned Secret Service agent Scot Harvath shifts his attentions to rooting out, capturing or killing all those responsible for the plot. As he prepares to close out his list, a bloody and twisted trail of clues points towards one man - the world's most feared, most ruthless terrorist, Hashim Nidal. Nidal has assembled an international league of Islamic terrorist networks in an ingenious plot to topple both Israel and America.

As a storm rages across the Mediterranean Sea, a terrifying distress call is made to the Italian Coast Guard. Days later, a body washes ashore. Identified as a high value terrorism suspect (who had disappeared three years prior), his name sends panic through the Central Intelligence Agency. Where was he headed? What was he planning? And could he be connected to the "spectacular attack" they have been fearing all summer?

The first agent disappearance was a puzzle. The second was a mystery. The third was a conspiracy. Intelligence operatives around the world are disappearing. When a missing American agent re-appears in Venezuela, Court Gentry, the Gray Man, is dispatched to bring him in, but a team of assassins has other ideas. Court escapes with his life and a vital piece of intelligence. Meanwhile, CIA agent Zoya Zakharova is in Berlin. Her mission: to infiltrate a private intelligence firm with some alarming connections. The closer she gets to answers, the less likely she is to get out alive.

Across Europe, a secret organization has begun attacking diplomats. Back in the United States, a foreign ally demands the identity of a highly placed covert asset. In the balance hang the ingredients for all-out war.
