Warning! The next attack on American soil will come from within. From coast to coast, the nation is witnessing a new wave of terror-suicide bombers incite blind panic and paralyzing fear, a flight attendant tries to crash an airliner, a police officer opens fire on fans in a stadium, and at CIA headquarters, a deputy director goes on a murderous rampage. The perpetrators appear to be American but are actually covert agents in a vast network of terror, selected and trained for one purpose only: the complete annihilation of America. Special Agent Jericho Quinn has seen the warning signs. As a classified "instrument" of the CIA reporting directly to the president, Quinn knows that these random acts of violence pose a clear and present danger, but he may not be able to stop it. The search for terrorists has escalated into an all-out witch hunt, and somehow, Quinn's name is on the list.
