Having lost their status and credibility five years after covering New York City with marshmallow in Ghostbusters (1984), the once-famous band of spirit-hunters find themselves struggling to keep afloat, working odd jobs. However, when Dana Barrett and her baby, Oscar, have yet another terrifying encounter with the paranormal, it's up to Peter Venkman and his fearless team of supernatural crime-fighters to save the day. Now, once more, humanity is in danger, as rivers of slimy psycho-reactive ectoplasm, and the dreadful manifestation of the evil sixteenth-century tyrant, Vigo the Carpathian, threaten to plunge the entire city into darkness unless the selfless Ghostbusters take action. Can they save the world for the second time?
