The storylines of the films follow a puzzle box that is a gate to the hell-like dimension of the Cenobites, an order of formerly human monsters who harvest souls to torture in sadomasochistic experiments.
Fitting right in with Freddy Krueger, Jason Voorhees, and other movie monsters, Hellraiser is a series of horror films that centers around a creature named Pinhead.
Pinhead is the leader of the Cenobites and the face of the franchise.
