Peter Venkman, Ray Stantz, Egon Spengler, and Winston Zeddemore are the Ghostbusters, the world's premiere (and only) paranormal investigation and elimination team. Hauntings? Possessions? They handle it all... for a fee. But when a enemy with the power to turn New York into a "city of the dead" attacks, the guys are put to the ultimate test! Now the Ghostbusters must confront their pasts, while trying to figure out how to defeat an adversary that can't be stopped by traps or proton beams for one simple reason - he's alive!
