A prisoner who is requesting asylum in the United States tells the government that there is a shipping container in which a group of terrorists is hiding, and that it is on its way to the U.S. Frankie is sent to Jarkarta to question the one man who might know if the government has been told the truth, and so, to find out exactly where the container is headed. Frankie gets the job done, but before she can get out of the country, she gets wounded and then caught. With the ""Threat Matrix"" team, from their headquarters (the ""Vault"") at Fort Meade, John Kilmer (the head of the ""Threat Matrix"" team *and* Frankie's ex-husband) works to find the answers they need to be able to neutralize the terrorist threat, even though doing that means that he has to leave Frankie to whatever fate awaits her until his primary job is done.
When a homicide detective becomes the victim of a terrorist car bomb, the Homeland Security team fears that a similar event is going to take place at a Veteran's Day parade that is planned for Washington, DC. Their investigation unearths the fact that a military munitions officer has been selling C-4 to terrorists and that the terrorists have been using money supplied by a Utah drug dealer to make their purchases. The team puts all of the pieces together in time to stop the terrorists from bombing the parade. The moral of the episode is that: ""We are, ironically, our own worst enemies. Terrorizing ourselves ... Fighting a war of dependency ... that, unfortunately, makes veterans of us all.""
When an Iraqi scientist who specializes in bio-weapons slips away from a U.S. operation to capture her, the Homeland Security Team becomes involved. During her escape, Dr. Hassan gives the keys to a car to the Iraqi family who helped to keep her hidden, then tells them that if they stop their car, the Americans will kill them. As a result, the husband, wife and child are shot at the border by a young American soldier, when they fail to stop at the checkpoint. Although Dr. Hassan murdered many people in the village in which she stayed while developing and testing her bio-weapons, the villagers still do not willingly assist the Homeland Security Team in gathering information that might aid in apprehending her, and ultimately, the American soldier who shot and killed the Iraqi family at the border is himself shot and killed by the villagers. Dr. Hassan is eventually apprehended, but no longer has the nerve gas in her possession, having passed it off to her assistant, who is preparing to
A dog from the Congo, infected with a new strain of Ebola, ends up in Amarillo, Texas. Because the daughter (Hannah) of the pet and feed store owner who ordered and received the dog is a cocktail waitress at a popular local bar, she ends up exposing dozens of people to the virus in one night. Although the outbreak is a natural one, the homeland security team takes charge, to prevent it from spreading. Their job is complicated by the fact that on the night that Hannah infected everyone, she and her ex-convict boyfriend (Shane) leave Amarillo and head to Las Vegas, where they plan to be married.
Considered an enemy combatant, a French-Algerian man is detained at Guantanamo Bay, Cuba. Because Frankie refuses to allow him to see a doctor while she is interrogating him, even after he tells her three times that he needs to see one, the man suffers a heart attack and dies. Whether it was because he was unwilling or unable, the Algerian national never directly gave Frankie any of the information she was trying to get before he died, and she ends up in a courtroom, first disobeying the order to quietly accept a plea bargain, in order to keep the entire incident below the radar, then pleading ""not guilty"" to the charge of second degree murder, which means that the matter goes to trial. With Mo's help, Kilmer ends up saving Frankie from going to jail by using the information that was gained before the sleeper-agent died, to stop an assassination attempt that might have started a war in the Middle East, and then testifying in court about it on Frankie's behalf. As a result, Frankie is
The aide to the North Korean Deputy Foreign Minister (who is also his illegitimate daughter), is kidnapped by Korean drug dealers, who want to use her as leverage to influence the Foreign Minister's decisions.
