Egon has invited Peter to the opera, much to Peter's annoyance since he thought it was a baseball game (because Egon had referred to the Metropolitan Opera as the "Met" and Peter's team is the Mets). They begin watching the opera, but when "Ride of the Valkyries" plays, real Valkyries (singing, overweight women in Viking garb who ride flying horses) show up. They cause chaos, and Peter and Egon eventually save the life of a diva, upon whom Peter has a crush.
The two decide to get rid of the Valkyries (along with Ray and Winston), but to Peter's displeasure, Egon (who has an appreciation for art) convinces the opera people to have them do it for free. The next morning, the Ghostbusters show up, and a janitor tells Winston that the Phantom of the Opera is haunting the building. This concerns him, but Egon assures him that the Phantom of the Opera is only a movie character.
The diva makes Peter her bodyguard (which he mainly uses as an excuse to lie around and ogle her) and the others follow the PKE readings to the roof. The Valkyries show up and the Ghostbusters attack them, but they miss, almost fall off the roof, and the Valkyries escape. The Ghostbusters track the Valkyries into the basement but can't find them, yet they return when Leopold the conductor rehearses.
The Ghostbusters try to warn Leopold that the Valkyries are attracted to "Ride of the Valkyries", and tell him to cancel the show, but he refuses, and sure enough, they show up. The diva dumps Peter (revealing that she never returned his affections and was only exploiting his feelings for her to make Leopold jealous), who is then kidnapped by the Valkyries, who threaten to take him away to Valhalla (which is "one of those places you never come back from"). The other Ghostbusters manage to trap the Valkyries and save Peter, but then it turns out that the Phantom of the Opera is real. However, he decides to leave due to the noise bothering him.
