A new display comes to New York of an ancient type of machinery thats called The Infernal Machine. Legend has it that the builder got the idea from an angel in a dream, but after building the machine it came to life and destroyed the city. Lately Roland has been flexing his creative muscle and building new technology only to feel unappreciated; then after a routine bust the Ghostbusters find that their equipment is malfunctioning and worse then that Roland doesn't seem to be around and keeps talking about his machine. When it turns out Roland has built his own infernal machine its too late; will history repeat it self?
- Roland: "I must work on my machine."
