The movie stars an adorable dog named Indy in his debut feature film, in which he "tracks an invisible presence only he can see, perceives phantasmagoric warnings from a long-dead dog, and is haunted by visions of the previous occupant's grim death." Per the synopsis, when his owner Todd "begins succumbing to the dark forces swirling around the house, Indy must battle a malevolence intent on dragging his beloved Todd into the afterlife." Good Boy hits theaters October 3.
