After a convenience store visit gone wrong, bunch of would-be Halloween partiers find refuge in the Hull house, and becomes targets for the demonic Angela.
This film has examples of:
- Becoming the Costume: Angela fuses Orson with his devil mask, and later turns Abby, who is dressed as Cat Girl, into a feline demon.
- Beat Still, My Heart: Angela kills Dewhurst by ripping out his heart. Then she says the trope name as a Bond One-Liner.
- Femme Fatalons: Possessed Abby develops these to with her new literal Cat Girl appearance.
- Fight Scene: Brief fight breaks out between Vince and Nick.
- Guns Do Not Work That Way: While Angela is seducing Orson, he asks her if she could suck a golfball through a garden hose. She then proves better by taking his revolver in her mouth and sucking all the bullets out of it.
- In the films defense, Angela is able to do various things which defy the laws of physics, such as teleporting or morphing. Those powers together could be used to suck the bullets out. However yes, the scene is absurd by the rules of the real world (hot though).
- Kiss of Death: Angela impales Orson through the mouth with her tongue during a kiss.
- Retirony: Played with. It's Lieutenant Dewhurst's last day on the force, but he actually manages to live long enough to retire before he is killed by Angela.
- This Is for Emphasis, Bitch!:Angela: Happy Halloween, bitch!
- Yo Momma: Reggie cracks couple of these jokes in the early moments of the movie.
- The X of Y: Used for the title, with the addition of Numbered Sequels.
