After The Boys get scared by the 5th Graders at the South Park Docks, they decide to get back at them. Stan comes up with the idea to scare them with a dead body and realizes they need a real dead body to be really scary. He decides to dig up Kyle's grandmother Cleo Broflovski at the Mt. Peaceful Cemetery, much to Kyle's horror. When they get to the cemetery, Cartman scares Kyle by pretending to be his grandma's voice.
Later on, two watchmen for the cemetery visit Sheila to tell her that someone had defiled her mother's grave, describing in extreme detail what they believe the grave robbers did to her body.
