With the inter-dimensional teams still shuffled and scrambled from the previous issue, the Ghostbusters are managing a Firehouse overrun with Slimers from multiple dimensions. Walter Peck and Jenny Moran field the administrative chaos while the teams are deployed across several missions simultaneously.
One team encounters the Headless Horseman and a haunted location tied to the Wander Hills Orphanage, which burned down in 1920 after lightning struck and caused a fire. Another crew investigates the Helsingor Brewery in Dimension 75-B. In a supernatural game of chess, Eduardo Rivera of Dimension 68-E faces Death, with the opening move being the Queen's Pawn to D4 (the Queen's Pawn Game). Egon Spengler and the team must also contend with the Hungry Manitou conjuring the Giant Murder Clown and Fire Goblins menacing another front.
Meanwhile, the larger threat comes into focus. Tiamat, who previously made a deal to leave the Ghostbusters' earth, is looking for loopholes in that agreement. Her father Koza'Rai appears and warns her she will regret her decision, referencing the Ghostbusters' victory over him during the events of Ghostbusters: Displaced Aggression. Koza'Rai reveals that Tiamat's attention was caught by the capture of The Collectors in Teenage Mutant Ninja Turtles/Ghostbusters Volume 2 #5. The issue closes with Holtzmann being grabbed and Ron Alexander injured.
