This is a pretty film from the 80's with all the usual 80's stuff. Kids from school are played by adults. They steal a box from a museum and find a scroll and use it to raise demons. Most of them are zombies, there is a werewolf and a vampire. One called Sandy is a helpful ghost. The party was silly and the dance scene was funny, because there were zombies crashing that party joining in! The ending was a tragic love story.
