Comedy with 3 guys at the beginning chasing an ambulance

After losing their academic posts at a prestigious university, a team of parapsychologists goes into business as proton-pack-toting "ghostbusters" who exterminate ghouls, hobgoblins and supernatural pests of all stripes. An ad campaign pays off when a knockout cellist hires the squad to purge her swanky digs of demons that appear to be living in her refrigerator.

Having lost their status and credibility five years after covering New York City with gooey roasted marshmallows in Ghostbusters (1984), the city's former heroes and once-popular spirit-hunters struggle to keep afloat, forced to work odd jobs. However, when Dana and her baby have yet another terrifying encounter with the paranormal, it is up to Peter Venkman and his fearless team of supernatural crime fighters to step up and save the day. Once more, humankind is in danger, as rivers of slimy psycho-reactive ectoplasm, paired with the dreadful manifestation of evil sixteenth-century tyrant Vigo the Carpathian, threaten to plunge the entire city into darkness. Is the world ready to believe? Can the Ghostbusters save us for the second time?
