Birdie and Alden Case have reconciled their differences and discovered a new passion in their marriage - private investigation work. Despite their past struggles, they are now enrolled in a private investigator course at the community college. Their newfound interest leads them to encounter Birdie's high school "friend" Kristen Duckburn and her new boyfriend, Police Officer Tom "Air Quotes" Newton. Tom initially refuses to involve them in his investigations but eventually seeks their help in solving the murder of true-crime author Laurel St. James. As they delve into the case, they suspect that the killer may be the same person Laurel was about to expose as the Roxdale Killer. The Cases navigate through various suspects, including voice-over artist Pat, yoga instructor Wintress, and aspiring podcaster Katie Hiller. Meanwhile, they also deal with a mouse problem in their home, adding another layer of complexity to their investigation. Alden's fear of mice further complicates the situation.
