In this modern take on Charles Dickens’ “A Christmas Carol,” Frank Cross (Bill Murray) is a wildly successful television executive whose cold ambition and curmudgeonly nature has driven away the love of his life, Claire Phillips (Karen Allen). But after firing a staff member, Eliot Loudermilk (Bobcat Goldthwait), on Christmas Eve, Frank is visited by a series of ghosts who give him a chance to re-evaluate his actions and right the wrongs of his past.
Strange and creepy happenings beset an average California family, the Freelings — Steve (Craig T. Nelson), Diane (JoBeth Williams), teenaged Dana (Dominique Dunne), eight-year-old Robbie (Oliver Robins), and five-year-old Carol Ann (Heather O’Rourke) — when ghosts commune with them through the television set. Initially friendly and playful, the spirits turn unexpectedly menacing, and, when Carol Ann goes missing, Steve and Diane turn to a parapsychologist and eventually an exorcist for help.
After the members of a team of scientists (Harold Ramis, Dan Aykroyd, Bill Murray) lose their cushy positions at a university in New York City, they decide to become “ghostbusters” to wage a high-tech battle with the supernatural for money. They stumble upon a gateway to another dimension, a doorway that will release evil upon the city. The Ghostbusters must now save New York from complete destruction.
