Prime Evil ordered the Witch of Salem to scare Corky, Bones and Hermie Winslow at a haunted house in Salem, Massachusetts to bait a trap for the Ghostbusters. When the Ghostbusters entered the Haunted House, Prime Evil told Brat-A-Rat to switch on the Scareway and send the Ghostbusters back into the past, to 1692, the year of the Great Witch Hunt.
