After Sissy’s breakup, she packs a bag; picks up her Yorkshire terrier Duke; and leaves Tulsa, Oklahoma, bound for her parents’ former hometown. There are still plenty of Yoders in Yoder, Kansas, including Sissy’s aunt Bethel, who owns the Sunflower Café but recently broke her leg. She begins to run the cafe with her cousin Lizzy. Sissy finds the milkman out behind the café with a knife in his back. As the sheriff’s prime suspect, it’s up to Sissy to catch the backstabber herself—before someone else gets creamed.
