Ghostbusters (1984)

Who you gonna call? How about three parapsychologists (ghost scientists) who started a New York ghost-busting business to rid Manhattan of all its spooks? Ego, Ray, and Peter lose their research grants at their university and open Ghostbusters, and they soon find themselves investigating the possession and abduction of a woman who Peter was planning on going on a date with. It turns out, ghosts aren’t as rare in New York as people think.
