Fifteen-year-old slacker Charlie Harker is stuck in the sleepy town of Rolling Hills for the summer, helping his mom renovate his great-grandfather's creaky old inn. It's not entirely dull, thanks to Charlie's new neighbor Miles Van Helsing, who insists there's paranormal activity happening in Rolling Hills. Charlie chalks it up to Miles being the town nutcase. But many townspeople are falling prey to a mysterious illness, and wisecracking Charlie quickly gets wise: there's something sinister going on in Rolling Hills.
