CIA counterterrorism agent Jack Swift is a top operative within the agency. He is assigned to bring down key terrorists on a worldwide basis. He began his career working cross Mexican/US border terrorism with the agency. During a stint in the Middle East working with the Mossad, he manages to take down a well-known Iranian nuclear physicist. Through forensics and paper evidence, Swift and his team uncover an elaborate scheme to funnel radioactive material, money, and weapons to drug cartel gangsters operating throughout South America, Central America, and Mexico. This is a new kind of enemy for the agency, one right in their backyard. Through quick thinking and great knowledge of the cartel's operation, working closely with other government and state agencies, Swift and his team manage to avert a major catastrophe scheduled to be undertaken on the anniversary date of 9/11.
