Arriving in Summerville, Phoebe soon begins exploring, eventually encountering and befriending the ghost of her grandfather. Though he isn’t seen, he leads her to his work underneath the barn where he’s hidden his original Ghostbusters equipment, including the Ecto-1. After Phoebe shows a ghost trap to her teacher Gary Grooberson (Paul Rudd) and her new friend, who for some reason goes by Podcast (Logan Kim), Gary realizes that Phoebe is the granddaughter of an original Ghostbuster and reveals to her the legacy she’s stumbled upon. After Spengler’s ghost helps Trevor fix up the Ecto-1, he takes Phoebe and Podcast for a ride where they capture their first ghost, Muncher.
In true Ghostbuster fashion, they cause a ton of damage around their small town, and their equipment is seized by the local authorities. Thankfully, Trevor has a crush on the Sheriff’s daughter Lucky (Celeste O’Connor), who ultimately helps get their stuff back. In the meantime, Phoebe attempts to get Ray Stantz to come and help, but he explains that the Ghostbusters are long gone and that he feels somewhat betrayed by Spengler for leaving in the first place. The new crew doesn’t have time to dwell on that, as Ivo Shandor is revealed to be alive in his coffin and helping dismantle Spengler’s safeguards, allowing Gozer to finally cross over — but only after Zuul and Vinz Clortho possess Callie and Gary, of course.
