Saw IV (2007) is a film in the Saw horror series.
Warning: Spoilers in Synopsis.
Having been killed at the end of the previous movie, his body is soon sent to the morgue for autopsy. However a tape is found within his stomach and a detective, Matt Hoffman, is called in to investigate. Playing it reveals that though Jigsaw is gone, his work will continue. And indeed a young cop named Daniel Rigg finds himself thrust into one of Jigsaw's games with the lives of Eric Matthews and Hoffman on the line as he makes his way though the city to find clues to their location, finding other unfortunates along the way who are likewise in the midst of Jigsaw's deadly game.
This film provides examples of:
- Asshole Victim: Brenda (the pimp), Rex (the abusive husband) and Ivan (the serial rapist) all qualify.
- Big Damn Heroes: Subverted by Rigg in the beginning and done right by him in the end, much to Eric Matthew's and Art Blank's disappointment.
- Big "NO!": Rigg, right when he fails his test and gets Eric killed. Notice a pattern here?
- Chronic Hero Syndrome: The flaw Rigg is being tested for, and that he ultimately fails to overcome.
- Disposable Sex Worker: Brenda, a pimp and the woman in the Hair Trap, who Daniel Rigg is told not to save, but saves anyway only to have her attempt to kill him as part of her "test" from Jigsaw but Rigg ends up killing her in the ensuing fight.
- Domestic Abuser: One of the Asshole Victims in this installment. He and his wife are strapped back to back, with spikes going through both of their bodies in such a way that they pierce his major arteries but not hers. Jigsaw means for the wife, who has suffered physical abuse at his hands and did nothing to stop him from abusing their daughter, to yank the spikes out herself, killing her abuser and enabling her own escape. She does.
- Dropped a Bridge on Him: Jeff Denlon is unceremoniously shot to death by Strahm a few seconds after the events of Saw III, in which he was the protagonist, and before he can even begin to play the game to save his daughter.
- Idiot Ball: When inspecting dangerous weapons, it's probably a good idea for everyone to move out of the damn way. A forensics officer died for standing in front of a crossbow that discharged while another was dusting it for prints.
- Eye Scream: One trap forces the victim to pierce their eyes or be dismembered. The victim in question manages to successfully get one done before getting torn apart.
- Flayed Alive: Rigg's first test involves a woman strapped to a machine that slowly tears her scalp from her head by threading her hair through a set of gears.
- Footnote: That wouldn't happen in real life. The hair would rip and tear before the scalp would. Hair might be strong, but it's not that strong.
- Mouth Stitched Shut: Art Blank, the survivor of the mausoleum trap. Once it's over, he screams and the stitches rip out.
- Once More, with Clarity!: The first and last scenes are the same. It's in its proper chronological order the second time around.
- Precision F-Strike: While his test subjects swear heavily, Jigsaw barely used any foul language. While still reeling from the death of his son Gideon, John says "Get the fuck out of here," to a guy who was asking him if he was sure about cutting off his funding for Jill's drug-rehabilitation clinic.
- Reality Ensues: Jigsaw's first victim doesn't develop Stockholm Syndrome, forgive Jigsaw for putting him in a deathtrap, and become his apprentice. No, he's royally pissed off and once he gets out, he immediately bum-rushes him with every intent of kicking his ass.
- Riddle for the Ages: Unlike all the other victims, Trevor's reason to being targeted by Jigsaw was never explained.
- The Reveal: The film's events take place at the same time as the events of the previous film; Hoffman is Jigsaw's second apprentice.
- Sequencing Deception: The first scene is chronologically the last; everything else takes place during the previous film.
