Halloween 4: The Return of Michael Myers

On October 30, 1988, Michael Myers, who has been comatose for ten years since the explosion at Haddonfield Memorial Hospital, is being transferred from Ridgemont Federal Sanitarium to Smith's Grove Sanitarium. During the transfer, when Michael overhears that he has a niece living in Haddonfield, he awakens, kills the ambulance personnel and heads back to his hometown to kill her. Dr. Loomis, who also survived the explosion, learns of Michael's escape and gives chase back to Haddonfield once again. Rachel Carruthers, Jamie Lloyd's foster sister, finds herself forced to babysit Jamie that night after her date cancels, unaware of Michael's return.
