Ghostbusters

Three parapsychologists, Peter Venkman, Ray Stantz, and Egon Spengler (Bill Murray, Dan Aykroyd, and Harold Ramis), set up a ghost-catching business in New York City after losing their university jobs. They face a supernatural threat that could destroy the world, capturing ghosts and containing supernatural energy across the city with high-tech nuclear-powered equipment. The Ghostbusters hire Dana Barrett (Sigourney Weaver) to help them capture a gluttonous ghost from the Sedgewick Hotel, but things take a turn when they discover she's possessed by a demon named Zuul, who was summoned by a cult that designed her apartment building as an antenna to attract spiritual energy.
