After the young son of a British Intelligence officer is kidnapped and the man fails to report him missing, the CIA and British Intelligence's investigation takes an unusual turn. They learn that the man didn't report his child missing because the kidnappers are Iraqis and he has arranged to trade plans for an Allied invasion of Iraq in exchange for his son's return. Matt and Carl join the investigators in London to ensure that the officer's plan is derailed without losing the boy in the process. Meanwhile, Robert Quinn, who is temporarily replacing Director Pierce, starts implementing changes. Daniel Benzali (""Murder One"") guest stars.
