After saving New York City from the demi-god Gozer, the Ghostbusters are sued for property damage and barred from investigating the supernatural, forcing them out of business. Five years later, Ray Stantz owns an occult bookstore and works as a children's entertainer with Winston Zeddemore, Egon Spengler works in a laboratory conducting experiments into human emotion, and Peter Venkman hosts a psychic television show. Peter's ex-girlfriend Dana Barrett has had a son, Oscar, with an ex-husband, and works at an art museum.
