Plot
The Ghostbusters answer a call from Mrs. Hardenbauer, an elderly woman who reports that her husband has been acting strange, lurking around the house and seeming "off" even though he looks and acts the same. Garrett and Roland get no readings on their P.K.E. Meters, and Eduardo Rivera starts to suspect the wife herself. The team splits up to search the house. In the basement, Eduardo admires his reflection in a mirror when a red demonic entity leaps out at him. The others rush down to find his body on the floor and his soul drifting near the ceiling. Eduardo realizes he is dead.
A "new" Eduardo wakes up while the real Eduardo, now a ghost, watches the team walk straight through him. Back at the firehouse, Janine Melnitz and Egon Spengler are told the call was a false alarm. The possessed Eduardo communes with a demon through a restroom mirror and takes its orders: turn every mirror into a portal so the Ghostmakers can take over the city, and eliminate the team. He lures Slimer into the restroom and possesses him too, leaving Slimer's spirit to float beside the equally bewildered real Eduardo.
Small tells start to add up. The possessed Eduardo compliments Janine's sandwiches and eats one with mayonnaise, which the real Eduardo hates. Garrett Miller notices, and Roland Jackson brushes it off as changing tastes. When Garrett follows the possessed Eduardo into the kitchen and gets close to catching him turning dishes into portals, Egon calls the team out to another job: the Hardenbauers want to apologize for the false alarm. At the house, Roland's meter spikes, the couple's faces morph, and they bolt. The wife throws Roland into a row of trash cans with ease. While chasing the husband, Garrett is shoved into a full-length mirror by the possessed Eduardo and possessed as well.
Paranoia spreads through the team. The P.K.E. Meters turn up broken, sabotaged by the possessed Eduardo, and no one can tell who is compromised. Egon has Roland tune a thrower to a special frequency while Kylie lays down a Trap; they wrangle the demon out of Garrett's body, but the body has no pulse. Egon concludes they are facing Ghostmakers, demons that eject a victim's soul and inhabit the empty body.
In the demons' Mirror Realm, the leader confronts the captive Eduardo and Garrett and reveals he can inflict the agony of death a thousand times over. To fight back, Egon unveils his experimental Mass Maker gloves, built to make the ephemeral physical; a ghost who touches them while they are activated can be restored to a corporeal body. The possessed members overpower the team one by one, and Janine is possessed when she grabs the fire pole after the possessed Slimer touches it. Kylie slips in the bathroom, plays dead to fool the demons, then reaches the lab. When the possessed Egon tries to trap her by making her look into a pocket mirror, she turns it on him instead, then grabs the gloves and solidifies Roland and Egon.
With their bodies restored, the team blasts and traps the demons one by one, freeing each soul to return to its body. Slimer charges through the lead demon's head in the Mirror Realm and pulls Eduardo and Garrett toward the exit, but the demon grabs Garrett back and electrocutes him. Eduardo, returned to his body, fires into the mirror and drags the lead demon out, where Egon and Kylie hit it with crossing streams and Janine traps it. Garrett and Slimer return to their bodies. Kylie jokes that Eduardo nearly gave them seven years of bad luck, and the team smashes the mirror with a few miniature busts to be safe.

Notes
The Ghostmakers' scheme of possessing humans to seize the city echoes "Ghostworld," an earlier episode of The Real Ghostbusters.
Kylie calls the possessed townspeople "Stepford Guys," a nod to The Stepford Wives. When the possessed husband punches through a wall, Garrett yells "Freeze, Rocky!" after the boxer of the Rocky films; the Finnish dub renames the reference to Rambo, another Sylvester Stallone character.
The episode shows a rarely-seen part of the firehouse: a third-floor bathroom and the adjoining hall, plus a bathroom reached through the door beside Janine's desk.
This episode aired between "The Luck of the Irish" and "Slimer's Sacrifice."
