When Gracie is visited by a redheaded ghost, Officer Trudeau thinks the old gal is hallucinating. Again. But to Gracie the ghost is real, and her message is urgent: someone will die tonight.
Sure enough, a body surfaces in Echo Lake, and the little town of Coyne Falls plunges into chaos. Officer Trudeau is anxious to solve the murder, but he's far too busy searching for a missing vacationer, sizing up a secretive partner, and combing the woods for Gracie, who's off running errands for the dead.
Meanwhile, the ghost sends Gracie on a mission: follow the beagle to save a life.
