Halloween I (1978)

On Halloween night 1963, six-year-old Michael Myers (Nick Castle) stabs his seventeen-year-old sister Judith (Sandy Johnson) with a kitchen knife at their home in Haddonfield, Illinois at 45 Lampkin Lane. He is sent to Smith's Grove - Warren County Sanitarium in Illinois and placed under the care of psychiatrist Dr. Sam Loomis (Donald Pleasence). After years of treatment, Loomis begins to suspect that there is more to Myers than meets the eye and plans to have him committed indefinitely. Loomis, sensing that a tremendous amount of rage and emotion stir behind Myers's blank stare, describes Myers as "purely and simply evil". Myers escapes from Smith's Grove while being transferred and returns to Haddonfield. Loomis pursues Myers.
