Thirty-two years after defeating Vigo the Carpathian, the Ghostbusters have disbanded after a decline in supernatural activities in New York City. Egon Spengler has relocated to Summerville, Oklahoma, where occultist Ivo Shandor’s mining operations are located. Egon captures a bestial entity from Shandor’s mine, aiming to lure a potent entity to a painstaking setup in his acreage. When the trap-field’s capacitors fail, he hides the ghost trap that caught his captive under his farmhouse’s parlor floor. Egon struggles with another entity and suffers a fatal heart attack.
