New York City has a problem: paranormal occurrences have been plaguing the city in increasing numbers, and the only people who know this are three extraordinarily bright, slightly offbeat NYU parapsychologists who have lost their research grant. Forced out of academia, they start their own business. In this 1985 Oscar® nominee for Best Special Effects, Drs. Venkman (Bill Murray), Stantz (Dan Aykroyd) and Spengler (Harold Ramis) set up shop in an old firehouse and become Ghostbusters, trapping pesky ghosts, haunts and poltergeists for money. But even the spirit exterminators are severely tested when beautiful Dana Barrett (Sigourney Weaver) and her weird neighbor (Rick Moranis) become possessed by demons living in their building. Soon every spook in the city is loose, and our heroes face their supreme challenge at a rooftop demonic shrine.
