Santa Barbara Police Chief Carlton Lassiter is ambushed on the job and left for dead. In a vintage Psych-style Hitchcockian nod, he begins to see impossible happenings around his recovery clinic. Shawn and Gus return to Lassie's side in Santa Barbara and are forced to navigate the personal, the professional, and possibly the supernatural. Separated from their new lives in San Francisco, our heroes find themselves unwelcome in their old stomping grounds as they secretly untangle a twisted case without the benefit of the police, their loved ones, or the quality sourdough bakeries of the Bay Area. What they uncover will change the course of their relationships forever.
