As shown in the series finale, Shawn, Gus and Juliet relocated to San Francisco, where they remain three years later. After Juliet's SFPD partner Sam Sloan is shot, Shawn and Gus attempt to find out who was responsible and why it happened. They soon learn that a mysterious organization is threatening the reputation, safety, and well-being of Juliet. At first, Juliet is reluctant to allow anyone to help her out with her problem, but an unpleasant development connected with her partner's shooting convinces her she needs Shawn's help. Meanwhile, Shawn refuses to get married until he can locate his grandmother's engagement ring, which he had taken without permission from his dad's house, and which had in turn been stolen from him while he was in the very act of proposing to Juliet in San Francisco three years earlier. His efforts to retrieve the ring land him in hot water with an individual known as the premiere person fencing stolen goods in the Bay Area, with surprising results. Chief Vick, up for consideration for a position as police commissioner, is not aware that her daughter has fallen in with the wrong crowd. Gus, meanwhile, lands in hot water with his boss as a result of Shawn bringing his business to Gus's workplace, and is soon blown away when he has a run-in with an attractive woman who uses all the best moves in his own playbook. While working around all of these complications, the group encounters old friends, discover surprising pieces of information, and come to some major determinations about their futures.
