Named fifth worst movie villain, by the American Film Institute, Nurse Ratched is a cold, dictatorial nurse who controls a psych ward with an iron fist. From elevator music played loudly throughout the day to rigging group votes, Ratched finds ways to excacerbate the numbness the patients experience in the minds. All the patients follow who rules placidly until R.P. McMurphy (Jack Nicholson) joins the ward. Ratched catches on to his game and figures out ways to make his life more difficult.
