 It is still Halloween, 1978, and Michael Myers is on the loose after escaping certain death at Dr. Loomis  hands. By now, the entire sheriff s department is hunting for him, and Laurie Strode - his intended victim - has been taken to Haddonfield Hospital to be treated for wounds inflicted by Michael. Only Loomis & Sheriff Brackett- whose daughter had been murdered by Myers - seem aware of Myers  presence in the town, and a young man unknowingly alerts Myers to Laurie s location. When Myers reaches the hospital he eliminates virtually the entire staff in his pursuit. Meanwhile, Marion Chambers - who had been assisting Loomis during the planned pickup of Myers for his trial - meets up with Loomis to advise him that Myers is after Laurie for 1 reason: she is his sister - born 2 years before he was committed. Loomis is forced to overpower the U.S. Marshal who was to return him to Smith s Grove, and head for Haddonfield Hospital to stop Myers  blood spree. But are they too late?
