With her parents (guest stars Frances Sternhagen and Barry Corbin) in town, Brenda is busy preparing for her upcoming wedding. Duty calls, however, when a cell phone is found containing text messages that point to a possible homicide. The case becomes a race against time when the police realize there may be more than one killing involved. Tagging along for the investigation is Fritz's vegan sister, Claire (guest star Amy Sedaris), who fancies herself a psychic (or as she says, "an intuitionist").
