Ray and Winston are searching around the bedroom in vain for their baseball and sock respectively. Peter enters and initially thinks those guys are just scatty, but then he loses some food and a shoe. Meanwhile, two construction workers notice a glowing hole in the ground. They tell their boss, Big Ed, and think they should call the Ghostbusters, but Big Ed thinks they should fill in the hole instead. He does so, but this just widens the hole, so one of the workers calls the Ghostbusters anyway.
Meanwhile, Janine has lost her typewriter, and Slimer sees Peter's shoes walking on their own. However, when he tells Peter, he doesn't believe him... until he sees them for himself. The Ghostbusters get called out to the construction site (in Brooklyn), and Peter, Ray, Winston, and Slimer head out, but Egon stays behind to deal with high PKE readings.
On the way there, Peter and Slimer tell Ray and Winston about the shoes, but aren't believed. Then, a bunch of objects start floating up into the air, including pieces of the Ecto-1 and the road (which rolls up). Meanwhile, at the construction site, Big Ed wants to throw dynamite down the hole, but a cop tells him to wait until the Ghostbusters arrive.
When they do arrive, Winston reveals that Ed is his father, and then two demons in miner gear come out of the hole. The Ghostbusters blast them, then Ed detonates the dynamite. This initially closes up the hole, but the demon miners widen it, and the Zeddemores fall through.
Ray tells Egon about this on the radio and decides to drive down the hole despite Egon's warnings. When the guys and Slimer go through the hole, they find themselves in a dimension full of random odds and ends, in addition to bat-winged demons that appeared to be searching for something. Ray determines that this place is called the "Land of Lost Objects", which is just what it sounds like. Meanwhile, the Zeddemores are in prison. Winston picks the lock, but then a creature named the Collector appears, who reveals that he's searching for something and using the Zeddemores as insurance so the other Ghostbusters won't interfere.
Peter tries to fire at the bat-winged demons, but the proton packs apparently don't work in the Land of Lost Objects. Meanwhile, Egon is still working, only for the firehouse to get sucked into the Land of Lost Objects as well. Egon and Janine exit, and the former gives the others devices so the proton packs will work. The Collector reveals that what he seeks is a key, and it's been gone for ten thousand years. Everyone else parts a moat with the proton packs and approaches the castle.
They send Slimer in, since he's immune to the various traps, and he finds the Zeddemores. The Collector reveals that the key is meant to free him from the fortress, since he used to also be a ghost hunter but was imprisoned there by demons. Then, he notices Big Ed's necklace, which is a family heirloom, and reveals that it contains the missing half of the key. Ed gives the Collector the half, he joins them together, and everything (and everyone) is put back where it belongs.
