This artifact summons the Cenobites, extradimensional beings who deliver a form of extreme sensation that is indistinguishable from torture. The narrative then shifts to Frank's brother, Rory, and his wife, Julia, who move into Frank's former house, where Julia discovers a disfigured Frank trapped within the walls. Julia, still infatuated with Frank, begins to supply him with blood to restore his body, leading to a series of escalating horrors. The story culminates in a brutal confrontation where Rory and Kirsty, Rory's friend and unrequited admirer, become entangled in Frank and Julia's gruesome desires, ultimately revealing the true nature of the Cenobites' "pleasure."
