Extremities (1986)

Synopsis
Attacked by a masked assailant, Marjorie (Farrah Fawcett) lives in mortal fear that the unidentified man will strike again -- especially since he knows her address. Sure enough, Joe the attacker (James Russo) breaks into Marjorie's home and subjects her to a night of terror and sexual humiliation. But Marjorie manages to turns the tables on her attacker, knocking him unconscious and rendering him helpless. The remainder of the story charts Marjorie's battle with herself: should she turn Joe over to the authorities, who may very well set him free, or should she mete out her own punishment? ~ Hal Erickson, All Movie Guide
