Plot
In the Netherworld, a young ghost is accosted by a mean ghost who looks a lot like Slimer. The evil twin steals the ghost's lollipop and taunts him until the ghost's three older brothers arrive and corner the bully, who tricks them into looking away and flies off.
On the physical plane, Slimer and Louis play a game of Blackjack at the front desk. Slimer does not know the rules and clobbers Louis with a sub sandwich when Louis says, "Hit me." Janine returns and shows off her latest find, an antique mirror bought at a garage sale. The mirror is a gateway into the Netherworld, and as Slimer looks at his reflection the evil twin peers through from the other side and crosses over. While Slimer cleans green slime off the mirror in the kitchen, the twin ambushes him, bounces him around like a pinball, and shoves both Slimer and Louis through the glass into the Netherworld. The twin then spray-paints the mirror's surface black and tosses it into a passing garbage truck.
In the Netherworld, the ghosts mistake Slimer for his evil twin. Louis tries to defend him, but the brothers are not convinced, and the two run for it. Back at the firehouse, Egon Spengler and Peter Venkman drag themselves home covered in ectoplasm. Peter, eager to have Louis do his income taxes, finds a wrecked kitchen and the evil twin instead. The twin fakes sickness and bad behavior, screaming in Egon's face and cranking up the television. When Peter checks the firehouse security footage and sees two Slimers, the pieces fall into place. He and Egon suit up and trap the twin as it ricochets around the sleeping quarters.
Peter, Egon, and Janine drive to the city dump and use P.K.E. Meters to locate the buried mirror. Slimer and Louis, meanwhile, find an information desk and learn the last bus out of the century is leaving; they catch it but are quickly ejected and the chase resumes. Janine finds the mirror and Egon wipes the paint clear just as Slimer spots the gateway and dives through, crashing into Janine. Peter reaches through and pulls Louis out at the last second. Egon sweeps the mirror and confirms no spectral activity remains. Back home, they celebrate with another game of Blackjack, and Slimer bops Peter with a celery stick when he asks for a card.
