Halloween is just around the corner and Cait has a little something for everybody - until her father and his hundred-pound Bernard (who happens to be the unintentional Moriarty to her Sherlock) show up to turn her world upside down. In the midst of the chaos Cait is employed to discover the identity of the inside man responsible for a number of thefts at the Nakatomi dealership - and she soon discovers to her dismay that she isn’t the only one on the case. Speaking of cases, Trace has been assigned to a grisly murder in which the victim is dressed as a notorious Hollywood slasher. Is this a collage frat party gone awry or the beginning of a murder spree centered around the season? Movies collide as do dangerously stubborn personalities and if things continue to escalade there’s no telling who will end up with a bag of treats - and who will get stuck with the tricks.
