Synopsis: Pia Zadora stars in an over-cooked melodramatic adaptation of the 1946 James M. Cain novel that is every bit as smutty and sleazy as Zadora's vampish character of Kady. The location of the novel has been switched from Appalachia to the barren lands of Arizona and Nevada in 1937. Stacy Keach plays Jess Tyler, a desert hermit who has spent years guarding an abandoned silver mine. Suddenly, Jesse is confronted by his very grown-up and sexy daughter, who, when she was a baby, had been taken away from him by his wife, Belle (Lois Nettleton). Kady, it so happens, hasn't come home for a family reunion -- she has just been dumped by a rich young man who is the father of her illegitimate child and whose family owns the very silver mine that Jess is guarding. Kady hopes to use her feminine wiles to seduce Jess and reopen the mine and extract the money from the earth that she feels is due her from the family. As if his seductive daughter walking around bare-breasted in front of him isn't enough, Jess must also deal with the sudden return of his older daughter, Janey (Ann Dane), who appears with Kady's son; Belle, who comes back to Jess dying of tuberculosis; and Moke Blue (James Franciscus), the man who stole Belle away from Jess years ago. Also squeezing his way into Jess's shack is Wash Gillespie (Edward Albert), the father of Kady's child, who now wants to marry her. Butterfly also features Orson Welles as Judge Rauch.
