History Film / VHS

* Amateur Night: Three college guys plan on videotaping their sexual encounters and get more than they bargained for when they pick up a strange woman from the bar.
* Second Honeymoon: A couple on a road trip are stalked by a mysterious stranger.
* Tuesday the 17th: A group of twenty-somethings party in the woods and are stalked by an entity that can only be viewed via videorecorder.
* The Sick Thing That Happened to Emily [[LongTitle When She Was Younger]]: A girl talking with her boyfriend via webcam believes that she is being plagued by paranormal phenomenon.
* 10/31/98: A foursome heads to a Halloween party only to find out that the house hosting it is abandoned.

** A minor one on "Amateur Night". Shane wasn't outright evil, but his intentions for the night certainly were less than honourable, since the plan was to film the sexual intercourse without the girl's knowledge. But once Lisa falls unconscious in drunken stupor, he stops his attempts with her. The group may be voyeurs but they draw the line at statutory rape.

In 2016, a feature length film based on the concept introduced in "Amateur Night", ''[[Film/Siren2016 Siren]]'', was released, with Hannah Fierman [[RoleReprisal reprising her role]] as [[ADayInTheLimelight Lily]].

* ADogNamedDog: ''[[Film/Siren2016 Siren]]'', reveals Lily is a "Lilith". True to the original filmmakers' intent; despite many viewers' assumptions, she never was intended to be either a succubus or anything from actual mythology.
* AManIsAlwaysEager: [[DefiedTrope Defied]] like hell by both Clint in "Amateur Night" and Joey in "Tuesday the 17th" - both are put-off by the circumstances (Clint's [[spoiler: broken arm and recently-murdered friends]] and Joey [[spoiler: being told a ''very'' flimsy excuse about the absence of their friends]] before being propositioned.).

* {{Jerkass}}: Everyone in the movie except for Emily in "The Sick Thing That Happened to Emily When She Was Younger", and the guys in "10/31/98", who are merely GenreBlind.
** Arguably Clint as well in "Amateur Night", considering that while he was [[SpyCam in on]] Patrick and Shane's little sexcapade, he [[TheLoinsSleepTonight wasn't]] ''[[AManIsAlwaysEager that]]'' desperate.

* The Sick Thing That Happened to Emily When She Was Younger: A girl talking with her boyfriend via webcam believes that she is being plagued by paranormal phenomenon.

* AlwaysSaveTheGirl: The guys in "10/31/98" go back to save the poor captive girl. [[spoiler: Unfortunately, once they reach [[RailroadTracksOfDoom railroad crossing]], [[FalseInnocentTrick the favor is not returned]].]]

* FalseInnocenceTrick: Possibly, in [[spoiler:"10/31/98,"]] if [[spoiler:the demon were escaping an [[HollywoodExorcism exorcism]] and not an instance of EvilInc, HijackingCthulhu as in ''Film/{{Siren}}'']].

* ShownTheirWork: Whether by accident or design, any time the video-cameras pass over a TV-screen, the screens flicker, which was common in the old CRTs shown in the movie.

** In "Second Honeymoon", Stephanie and Sam use an electronic fortune-telling machine, and by the end of the segment, both of their fortunes come true in a twisted way: [[spoiler: Sam gets a fortune about someone close to him not being trustworthy, and ends up betrayed and murdered by his wife. Stephanie gets one about having a happy reunion with someone, and she and her girlfriend leave together as {{Karma Houdini}}s]]

** In full force during "Second Honeymoon", when, after their encounter with a would-be hitch-hiker after dark, [[spoiler: said hitch-hiker is ''in their room'', recording them both with their own camera while wielding a switchblade]]. Nothing happens that night.

** Arguably Clint as well in "Amateur Night", considering that while he was in par with Patrick and Shane's little sexipade, he wasn't ''that'' desperate.

* CrapsackWorld: If indeed all the tapes, including the ones from the sequel(s?) take place in the same world then everybody is screwed. You have malevolent [[spoiler:aliens]], ghosts, monster/ghost/demons that look like digital glitches, succubi, an insane cult that brought a rampaging demon into the world and what looks like a ZombieApocalypse, an evil corporation (or at least a neglectful one), and [[ArsonMurderAndJaywalking psycho lesbians.]]

* AlwaysSaveTheGirl: The guys in "10/31/98" go back to save the poor captive girl. [[spoiler: Unfortunately, once she becomes possessed, the favor is not returned.]]

** A minor one on "Amateur Night". Shane wasn't outright evil, but his intentions for the night certainly were less than honourable, since the plan was to film the sexual intercourse without the girl's knowledge. But once Lisa falls unconscious in drunken stupor, he stops his attempts with her.

* KarmaHoudini: [[spoiler:[[PsychoLesbian Stephanie and her lover]], who kill Sam and escape.]]

* WhatHappenedToTheMouse: Lisa's fate in "Amateur Night". It is likely that she survived [[spoiler:since it seems that Lily is a succubus-like creature who only shows interest in men]], but we have no visual confirmation. After all, she was lying unconscious just a couple of feet away from the creature, so who knows?

%%* BitchInSheepsClothing:
%%** [[spoiler: Wendy]] in "Tuesday the 17th".
%%** [[spoiler:James]] from "The Sick Thing That Happened to Emily When She Was Younger".
%%** [[spoiler: Stephanie]] from "Second Honeymoon"

* ADogNamedDog: ''{{Film/SiREN}}'', reveals Lily is a "Lilith". True to the original filmmakers' intent; despite many viewers' assuptions, she never was intended to be either a succubus or anything from actual mythology.

** Made all the more meaningful by {{Film/SiREN}} and its revelation that [[spoiler: Lily's species mates for life]]

** Lily's head bump thing is a lot more natural looking in ''{{Film/SiREN}}''.

** {{Film/SiREN}} takes this further - there's a SinisterMinister running a hedonistic business using demons that killed those who summoned them but failed to control them. There are enough demons running loose due to screwed-up summoning that ''someone can make a living off it''.

* {{Yandere}}: ''{{Film/SiREN}}'' reveals [[spoiler: Lily to be this - she isn't a succubus, doesn't kill through sex, and really doesn't appreciate people trying to kill her mate, and she would've killed the protagonist's wife if he hadn't gone to live with her.]]

In 2016, a feature length film based on the concept introduced in "Amateur Night", ''{{Film/SiREN}}'', was released, with Hannah Fierman [[RoleReprisal reprising her role]] as [[ADayInTheLimelight Lily]].

** [[spoiler:Last we see of Clint from "Amateur Night", poor guys being carried off somewhere by Lily, screaming the entire time.]]
** Possibly also [[spoiler: Wendy, if her thrashing was that of a disemboweled woman in agony and not a side effect of becoming another Glitch]].

** And when Gary finds [[spoiler: the bodies of his friends]], the appropriate reaction ''probably'' shouldn't be to laughingly say "Oh, fuck".

* BigBadEnsemble: The various conflicts are driven by [[spoiler:Lily, Stephanie, her unnamed lover]], [[HumanoidAbomination the Glitch]], a group of {{aliens|AreBastards}}, and a demon.

* ADogNamedDog: ''SiREN'', reveals Lily is a "Lilith". True to the original filmmakers' intent; despite many viewers' assuptions, she never was intended to be either a succubus or anything from actual mythology.

* BodyHorror: In ''Amateur Night" Lily starts out with scales on her feet, which [[OnlySaneMan only Clint notices]], and as things get worse she gets a strange maw-like crease down her face. [[spoiler: At the end she goes outright OneWingedAngel]]. This is also the subject of "The Sick Thing That Happened To Emily When She Was Younger"; at first Emily gets a small bump on her arm, which she suspects is from bruising. Later she [[spoiler: digs inside her arm with a scalpel and a kitchen skewer after suspecting something in there]]. But the crowning moment has to be [[spoiler:the reveal that she's pregnant with an alien spawn... and it's heavily implied this isn't the first time.]]

* DeathBySex: "Amateur Night", [[HornyDevils for obvious reasons]]. It crosses over with KarmicDeath.

* ApocalypticLog

* BitchInSheepsClothing: [[spoiler: Wendy]] in "Tuesday the 17th". Also [[spoiler:James]] from "The Sick Thing That Happened to Emily When She Was Younger". But the crowning example would be [[spoiler: Stephanie]] from "Second Honeymoon"
