The plot revolves around two recently deceased ghosts, Adam Maitland (Alec Baldwin) and his wife, Barbara, (Geena Davis), who seek the help of an obnoxious bio-exorcist, Betelgeuse (Michael Keaton), to remove the new owners of their house -- a family of metropolitan yuppies from New York City named Deetz. The Deetz family consists of Charles (Jeffrey Jones), his second wife, Delia (Catherine O'Hara), and his teenage daughter Lydia (Winona Ryder).
