Kathy and Cheryl have received free tickets to a new horror movie. Once inside, though, what happens on the screen starts to happen in the theater, after a fellow theater-goer cuts her face on a ceremonial mask on display in the lobby, and before they know it, the cinema is over-run with man-eating demons. Produced by Creator/DarioArgento, and directed by Creator/LambertoBava, son of [[MarioBava Mario]].

The sequel, released in 1986, takes place a few years after the events of the first film. An apartment complex is taken over by demons after a girl is attacked by one that emerges from a documentary about said demons. The film then follows some of the tenants who attempt to survive.

!!!'''This movie contains examples of:'''
* AngryBlackMan: One of the patrons in the first film who was actually quite cool and helped take action. [[spoiler: too bad he dies pretty early.]]
** The aerobics instructor in the sequel basically takes the exact same role, and is even played by the same actor.
* AnyoneCanDie
* ApocalypticLog: The documentary in the sequel shows a group of teenagers accidentally reviving a demon and getting killed on-camera.
* ApologeticAttacker: [[spoiler: The aerobics instructor does this to a mother who is turning into a demon in front of her daughter's eyes before shooting her. The daughter is Creator/AsiaArgento by the way.]]
* {{Badass}}: Tony the pimp who is easily the most GenreSavvy character in the first movie. He also takes the most affirmative action to save the group. [[spoiler: Unfortunately, he dies.]]
** The same actor plays an {{Expy}} of Tony in the sequel where he is a body builder. He is shown even more proactive and could almost be considered a BigGood. Again, [[spoiler: he dies.]]
** Also, George and his ''pregnant'' wife from the sequel who [[spoiler:actually make it out alive.]]
* BigBad: Apparently Sally in the sequel.
* BlackDudeDiesFirst: Played straight with Rosemary in the first film, averted in the sequel with Sally, who is white.
* BodyHorror: The demonic transformations, especially that of the first victim; also, when a transformed girl starts having convulsions, only for a much more demonic-looking, fully-grown monster to [[ChestBurster erupt from her carcass]].
** In the sequel, we're treated to seeing how the demons deteriorate, which includes bleeding acidic blood and their flesh melting away. Another smaller demon erupts from the chest of [[spoiler: a child-turned-demon]].
* ChekhovsGun: The mask, supposedly found in the tomb of Nostradamus with a prophecy about "the coming of demons" after being unearthed. Needless to say it doesn't take long for it to fire, though.
** Also the [[spoiler: red motorbike and sword in the lobby. How nice of them to put them all in one spot.]]
* ChestBurster
* DecoyProtagonist: [[spoiler: Cheryl in the first movie]].
* DemonicPossession
* DespairEventHorizon: Some characters go through this when they found a possible HopeSpot in escaping the theater but it's another dead end.
* DumbMuscle: Some of the clients of the gym in the second film play this straight.
* EyeScream: happens (ironically) to a blind man when the first infected shoves her thumbs in his eyesockets. [[spoiler:the man still manages somehow to be the first to leave the cinema; unfortunately, that means by the time anyone else gets out the city is overwhelmed by the demons.]]
* FinalGirl: [[spoiler: [[GenderFlip Gender flipped]] in the first movie: George is the sole survivor after Cheryl ends up being infected]].
* TheFourthWallWillNotProtectYou: At the beginning of the second movie, a demon from a movie about a demon contagion becomes aware that it's being watched, and breaks out to start a new outbreak. By the way, you're also watching a movie about a demon contagion...
* {{Gorn}}
* HopeSpot: Several in the first film, the group finding a possible way out only for it to be a dead end. And [[spoiler: up until the last minute it seemed like George AND Cheryl were going to at least survive the horror film.]]
* ImAHumanitarian[=/=]ToServeMan: They may or may not be considered "human" once they turn.
* InfantImmortality: Averted in the second film.
* KillEmAll: [[spoiler: In the first film, only George survives, while in the second, only three survive.]]
* MusclesAreMeaningless: In the second film.
* OurZombiesAreDifferent: They're actually under DemonicPossession, and damn fast.
* RedHerring: [[spoiler: The ticket woman seems like she's part of all that is going on. Turns out she's innocent.]]
* RuleOfScary: Both films take this trope to a total UpToEleven.
* SlidingScaleOfComedyAndHorror: Both Demons and Demons 2 are horror movies with a lot of humor, both intentional and [[{{Narm}} unintentional]].
* TheStinger: The end titles for the first movie start to roll on the screen, while Cheryl [[spoiler: picks at a wound on the back of her neck]]... [[SubvertedTrope Subverted]] because [[spoiler: the credits disappear, Cheryl turns into a Demon, but is shot and killed before she can harm George. Then the car with George on it disappears from view and the credits finally roll]].
* TaintedVeins
* TheVirus: A single scratch of their claws, teeth or horns, or a single drop of the demons' [[{{Gorn}} copious bodily fluids]], and you're done for.
* WhatHappenedToTheMouse: Its not shown what happened to Ingrid, the teenage girl in ''Demons 2''. She is last shown surrounded by demons while trapped in a car and then in a jump cut, the demons are shown leaving. The only possible thing is [[spoiler: she got killed too.]] [[spoiler: [[FridgeLogic That doesn't make sense because they explicitly showed a dog become a zombie and a boy too but couldn't show her death or atleast her fate?]]]]
* YoungerThanTheyLook: The female lead of the sequel, Hannah, is 15. Also, she's the producer's daughter(not [[Creator/AsiaArgento that one]]).
* ZombieApocalypse
