Overview
Captain K9 tells the story of Elizabeth Blue and her imaginary superhero show Captain K-9. Elizabeth's mother is the manager at a local public access station, where Elizabeth and her brother Benji spend their time after school and occupy themselves by making a show in an unused part of the station starring Zachary, Elizabeth's dog. When Elizabeth's best friend, Jessica, experiences changes in her homelife, she withdraws. Elizabeth, unable to understand the issues Jessica is having, interprets them as villainous, and reflects that in her show.
