First four films in the supernatural horror franchise based on the novella 'The Hellbound Heart' by Clive Barker.
In 'Hellraiser' (1987), when sexual profligate Frank Cotton (Sean Chapman) opens a puzzle box purported to grant access to a place of unparalleled pleasure, he is taken away to be tormented by the resident Cenobites led by Pinhead (Doug Bradley). Frank's brother Larry (Andrew Robinson) and his wife Julia (Clare Higgins) then move into Frank's house where Larry inadvertently summons Frank's spirit.
Now trapped in a monstrous form, Frank asks Julia to supply him with victims so that he can regenerate, but the Cenobites will not let him go so easily...
'Hellbound: Hellraiser II' (1988) follows psychiatrist Dr. Phillip Channard (Kenneth Cranham) in his quest to reach the world of the Cenobites.
After freeing Julia Cotton from their world, he brings patients to her so that she can feed on them and regenerate, but Julia has her own plans for Channard... Meanwhile, Kirsty (Ashley Laurence), Julia's step-daughter, is tricked into travelling to Hell.
In 'Hellraiser III: Hell On Earth' (1992), reporter Joey Summerskill (Terry Farrell) battles Pinhead, who is now devoid of humanity and determined to lay waste to Earth.
If she is to defeat him, she must reunite his human spirit with his Cenobite form and use the puzzle box to send him back to Hell. However, if she fails, Pinhead will bring forth Hell on Earth...
Finally, 'Hellraiser: Bloodline' (1996) explores the origins of the Lament Configuration.
In 18th century France, Toymaker Phillip LeMarchand (Bruce Ramsay) is employed by the Duc de L'Isle (Mickey Cottrell) to create a puzzle box, unaware that it will be used to summon a demon, Angelique (Valentina Vargas). LeMarchand's bloodline is cursed and the fates of his descendents are now intertwined with those of Angelique and Pinhead, unless one of them can permanently seal the gateway to Hell...
