Here’s another horror movie sequel that is a GU story in its own right: Hellbound (Hellraiser II).
Like the first movie, Kirsty fights both human and otherworldly adversaries. Having been put in an asylum, she must escape the machinations of her evil psychiatrist, who has summoned back her evil stepmother from the Cenobites’ dimension, as well as the Cenobites themselves (led by Pinhead). She is also trying to rescue her father, who may still be trapped there. She is helped by a much saner psychiatrist, and by a fellow patient who has been mute for years. Together they must navigate the labyrinthine (and carnivalesque!) otherworld.
Like many Girls Underground, Kirsty manages to defeat her adversary through clever trickery – however because this is the Hellraiser universe, it involves donning the bloody skin of her stepmother. Ew.
