Plot
Gilly Noble takes a stray cat named "Ringo" to the animal shelter where he works in Shelbyville, Indiana. Gilly gets his hair cut by a beautiful young aspiring hairdresser named Jo Wingfield. As Jo cuts Gilly's hair, she mentions that she recently lost a tail-less cat named Ringo, leading Gilly to tell her that Ringo is at the pound. The excitement causes Jo to accidentally cut off a part of Gilly's ear, and he is rushed to the hospital where the ear is reattached. To make up for the incident, Jo invites Gilly to her house for lunch the next day, where Gilly meets Jo's greedy, self-centered mother, Valdine, and invalid father, Walter.
Gilly and Jo date for six months before getting engaged, but suddenly a private detective, Vic Vetter, contacts Gilly to tell him that he's Valdine and Walter's son. After Gilly and Jo end their incestuous relationship, Gilly moves in with his new family, and Jo moves to Beaver, Oregon to start a new life. After being branded a "sister-fucker", Gilly loses his job at the animal shelter and is forced to take a job removing roadkill for the highway department.
