With Grace and Ham trying out new relationship and sex techniques, their games are interrupted when Grace's favorite Aunt Cathy comes to town and in the process of 24 hours, she has a run in with Earl at a local bar, clashes with Betty, goes out drinking and smoking with Grace and Rhetta, and reveals some shocking news. Meanwhile, the arrogant and pig-headed cattle tycoon Alvin Green's world begins to crumble after his lucky bull statue is stolen. He insists that the Major Crimes unit take the case, but Grace refuses to look into it knowing how ungrateful the snobbish Green is. Grace's father has a fire station named after him, and the family family comes together for the dedication ceremony. Also, police pathologist Henry's cat dies, and Grace comforts him the only way she knows how.
