After being arrested for the murder of Norman Keyes, Steele has to sit in jail while Laura and a mysterious stranger try to solve the case. It isn't long before Steele joins them - Mildred organizes a jailbreak.
Upon returning from their "Honeymoon" Steele and Laura learn that a new INS officer has been assigned to their case, who is a little more by the book. A woman from Steele's past comes back, just as he and Laura are trying to settle in. And Tony also shows up.
The Steeles learn that Shannon will go away if they help her get out from a blackmail scheme, and Tony is willing to drop Remington's immigration case if they help Tony find a mole in the intelligence service.
Tony is publicly and falsely accused of being a double agent, so Remington and Laura agree to hide him in their inherited Irish castle. Daniel Chalmers shows up and is extorted by an old female friend to turn Tony in to the KGB.
