The Hellworld script is based on a short story called "Dark Can't Breathe" by Joel Soisson[2] and was originally not planned as a Hellraiser film – it was reworked into that format.

Hellraiser: Hellworld was released straight to DVD in the United States on September 6, 2005, after a handful of minor film festival and private screenings.

Jake, who is still very much distressed by Adam's death, only agrees to show up after a female Hellworld player with whom he has struck up an online friendship asks him to attend so they can meet.

The quintet are cordially welcomed by the middle-aged party host, who offers them drinks, shows them around the mansion (allegedly a former convent and asylum also built by Philip LeMarchand), and provides them with cell phones to communicate with other guests.

As the party progresses, Allison, Derrick and Mike find themselves trapped in separate parts of the house, and are gruesomely killed by the Host, Pinhead, and the Cenobite minions Chatterer and Bound.

Holing herself up in the attic, Chelsea finds items belonging to Adam, and discovers that the host is his father, who blames his son's friends for not helping break his addiction.

The Host informs them that they are just coming out of a hallucination induced by a powerful psychedelic to which he exposed them upon their arrival, and that the events they have been experiencing have been the result of hypnotic suggestion and their own guilty consciences.

Jake and Chelsea are shown driving into the sunrise, when they receive a mysterious phone call from the Host, who suddenly appears in the back seat.
