The Ghostbusters want a vacation one night, so Ray suggests they go to his cousin Sam's dairy farm. Peter is not on board with this, but he and the others (plus Slimer) eventually end up going anyway. On their way, they end up crashing into a harvester. The driver directs them to the farm and tells them that his brother can repair the car, but it would take until Sunday.
They arrive at the farm at sunset, and Peter is still grumpy, but he perks up when he meets Ray's cousin Sam (short for Samantha) and falls for her. However, she doesn't return his affections. They talk about the farm over dinner, and then everyone goes to bed. At night, however, an undead rooster rises out of the ground, followed by several otherworldly hands.
The next morning, Sam finds the dairy a total mess. Egon scans the area and determines that a ghost probably did it, but Peter thinks they shouldn't do any work as they're on vacation. Ray and Winston, however, agree to investigate, so they do so, and are chased by a bull. Back in Sam's house, she reveals that the field has been barren ever since she bought the farm, and Egon extracts ectoplasm from some soil he dug up. Ray looks through the records and finds out that the farm used to belong to a family by the name of Peterson, who were all buried on the property, and when the cemetery was moved, the bodies weren't, so their spirits are angry.
They keep watch at night, and just when they start to lose hope that anything will happen, the undead rooster appears again, followed by the Petersons. Sam notes that they appear to be trying to do farm chores but accidentally causing messes. Ray tries to negotiate with them, but offends them instead, and they chase everyone angrily into the house. However, just when they're about to break in, it's sunrise and they disappear (just as Egon predicted they would). He explains that they're experiencing "chronometric reversal": in life, they worked all day, but now that they're dead, they work all night.
The Ghostbusters don't have their equipment with them, so Ray suggests they use the dairy's machinery to build something hold the Petersons in place. That evening, they build the device, and when the Petersons rise, they use it to trap them in an electric field. Sam tells them that they're destroying the farm, and Mr. Peterson agrees to leave so long as she plants daisies every spring. Thus, the Petersons disappear, then Slimer kisses Peter, so Peter chases him away.
