Ghostbusters

After their first encounter with an actual parapsychological phenomenon (a ghost) and losing their academic positions at Columbia University before they can follow up on their discovery, a trio of misfit parapsychologists – Peter Venkman (Bill Murray), Raymond Stantz (Dan Aykroyd), and Egon Spengler (Harold Ramis) – establish a paranormal exterminator service known as "Ghostbusters" at a retired New York City firehouse. While still facing dire straits after setting up the company, they are summoned by the Sedgewick Hotel to investigate a haunting. At the hotel, they capture their first ghost and deposit it in a "containment unit" located in the basement of their office. Paranormal activity soon increases in New York City, and the Ghostbusters become celebrities containing it, while at the same time becoming increasingly burdened by the hectic schedule. To satisfy increased demand, they hire a fourth member, Winston Zeddemore (Ernie Hudson).
