Venkman, Stantz, Spengler, and Zeddemore (Bill Murray, Dan Aykroyd, Harold Ramis and Ernie Hudson, again) discover that the source of the pink slime underneathe the streets is the museum of art where Dana (Sigourney Waever) works, and is the form of all the hatred and negative emotions of New York's civilians, which is fueling the power of Vigo the Carpathian, a powerful evil magician whose spirit haunts a painting. Janoz (Peter MacNicol), Dana's boss, kidnaps her infant son Oscar and takes him to the museum. Dana follows, but is trapped as slime covers the building. The Ghostbusters, committed to an asylum by the mayor's assistant are released and hired to save the day. To break into the museum, they spray positively energized slime over the Statue of Liberty, bringing it to life, and march it down the streets, hoping to encourage the civilians to form a positive attitude, which succeeds. Successfully entering the museum through a skylight over the restoration room where Vigo's portrait is, the Ghostbusters hoze Janoz down with positively energized slime, freeing him from Vigo's power. Vigo materializes, immobilizes the Ghostbusters with his awesome power, and is on the verge of possessing Oscar, when the now reformed civilians sing to celebrate the new year, weakening him. Vigo then tries to possess Ray and succeeds, but his friends hose him with slime and blast Vigo's portrait. Ray is freed from Vigo's power as the evil carpathian is blasted with positively energized slime, weakening him enough to be pulled back into the painting where he explodes. The slime covering the museum breaks up. The Ghostbusters share some love and friendship, even with Janoz. Dana and Venkman get back together. They all notice that what was once Vigo's portrait, now has the ghostbusters, dressed as angels, with Oscar in the center. The ending credits begin as they all leave the museum, greeted by the cheers of the crowd outside
