Henry, Jessie, Violet, and Benny have never been to a drive-in movie theater before, but they're visiting a friend who owns one. The children love to eat popcorn in the car and watch movies under the stars. But strange pranks are disrupting the fun. One night the sound system starts playing loud music during the movie, and a couple of the theater employees seem to be hiding a secret. Then, late at night, a ghost is seen walking around the empty grounds of the drive-in! Could the old theater be haunted?
