It's October 30, 1988 and Michael Myers has been in a coma since his pursuit of Laurie Strode, 10 years ago, was finally stopped (events of H1 and H2). However when he is transfered from Richmond Mental Institute to Smith's Grove he awakes when he hears that he has a niece in Haddonfield and after killing the transfer crew he escapes. In Haddonfield, the niece, Jamie, has been adopted by the Carruthers family but keeps having nightmares about Michael (but she doesn't know who he is). On Halloween night, Jamie goes out trick and treating, little knowing that her murdering Uncle is following her and her step-sister Rachel. Rushing to her aid is Dr. Loomis and with the help of Sheriff Meeker starts to search the town for Michael and to find Jamie to protect her. But can anything stop Michael this time?

While the rest of his high school graduating class is heading to the same old grind of college, skateboarder Eric Rivers and his best friends, Dustin, a goal-oriented workaholic, and misfit slacker Matt have one last summer roadtrip together to follow their dream of getting noticed by the professional skateboarding world--and getting paid to skate. When skating legend Jimmy Wilson's skate demo tour hits town, the boys figure that as soon as he sees their fierce tricks, he'll sign them up for his renowned skate team immediately, right? Unfortunately, the guys are intercepted by Jimmy's road manager and they can't get their foot in the door, much less their boards. But they do get some free advice: keep skating, stay true to yourself, and stay in the game--if you're good, you'll get noticed. Following their dream-- and Jimmy's national tour--Eric, Dustin and Matt start their own skate team...
