Setting Saw, like its film predecessors, is set in the fictional
Saw universe in an unnamed city in the United States. The overlying storyline follows that of a man named
John Kramer. According to the backstory in the film
Saw IV, John encountered a series of events, including the loss of his unborn child, his diagnosis of an inoperable frontal lobe tumor, his divorce from his wife, and a suicide attempt that caused him to begin testing other people's will to live. These tests, which ironically killed many of his victims, and the fact that he symbolically carved a puzzle piece out of the flesh of his victims, soon earned him the alias "The Jigsaw Killer" from newspaper reporter
Oswald McGullicuty. Due to the chronology of
Saw, Jigsaw is still alive and his apprentice Amanda is still assumed to be a victim rather than an accomplice. In
Saw, Jigsaw has just concluded the bathroom trap of
Lawrence Gordon and
Adam Stanheight, an incident that occurred at the end of the first film.
David Tapp, a police officer who had his throat damaged by Jigsaw's knife and was later shot in the chest by a suspect named
Zep Hindle, has been healed and is brought to Whitehurst insane asylum, an abandoned sanitarium with a reputation for medieval tactics and frequent
patient abuse. The asylum has many areas, most of which contain a key trap scene for Tapp to solve. A large part of the asylum consists of cells that were at one time used to hold the criminally insane. Jigsaw placed traps all around the asylum to continue his tests of will for Detective Tapp and his apprentice,
Amanda Young, who monitors Tapp as the story progresses.
Characters Saw revolves around the Jigsaw Killer and his test subject Detective David Tapp, the games'
protagonist. Jigsaw, a serial killer who is determined to spend the remainder of his life making people appreciate their lives, gives clues to Tapp as he progresses through the game. Clues are usually delivered by Jigsaw's puppet
Billy. Tapp is a veteran detective for the local police force who was recently discharged for mental instability after the loss of his partner,
Steven Sing, an event which led him to develop an obsession with catching Jigsaw. Throughout the game, Jigsaw attempts to teach Tapp to let go of his obsession and focus on survival. In addition to Tapp and Jigsaw, there are six main characters who Tapp must save throughout the game. Amanda Young is a drug user who is secretly Jigsaw's apprentice.
Jennings Foster is a corrupt
CSI who framed an innocent citizen for a hit and run he committed.
Melissa Sing is the wife of Tapp's former partner, Detective Steven Sing. She blames Tapp for her husband's death and has since become a neglectful parent to her son. Oswald McGullicuty is a newspaper reporter who coined the name "Jigsaw Killer" and accused Tapp of being Jigsaw.
Obi is an arsonist who seeks a test from Jigsaw to give his life a purpose.
Jeff Ridenhour is the second survivor of Jigsaw's games, and has become suicidal after Tapp interrogated him relentlessly about Jigsaw. There are also minor characters spread around the asylum. Most of these people have instructions to kill Tapp and obtain a key placed inside his chest by Jigsaw to free themselves. Some of the attackers have a "reverse bear trap", and some have a "Venus flytrap". Others are equipped with new, unique traps, and some have no traps at all. While not an attacker, a masked figure called "
Pighead" is the
antagonist. Pighead pursues Tapp around the asylum and watches over Tapp's game as per Jigsaw's instructions. At the end of the game, Pighead becomes the only
boss battle.
Plot The story centers on the kidnapping of
David Tapp by the Jigsaw Killer. During the first
Saw film, Tapp witnessed his longtime friend and partner, Detective Steven Sing, fall victim to one of Jigsaw's traps. This left Tapp mentally unstable and he was soon discharged from the police force. Later, Tapp was shot in the chest by
Zep Hindle after chasing him in pursuit of Jigsaw. Jigsaw had Tapp healed and concealed a key in his chest. Tapp was then placed in an abandoned insane asylum. Tapp wakes up in a bathroom with the reverse bear trap on him. He quickly pulls it off and ventures into the rest of the asylum. He is led to a medical wing by another victim of Jigsaw, only to be betrayed by the man. Tapp learns that he is being hunted by other victims in the asylum who need the key inside his chest to escape their own games. In the medical wing, Jigsaw informs Tapp that there is a woman trapped in the area who needs Tapp's help to survive. He quickly deciphers that it is Amanda Young, whom Tapp interviewed after she survived her first test. He saves Amanda, and she follows Tapp until a mysterious figure called Pighead captures her to fake her escape; she is actually Jigsaw's secret apprentice. Tapp is forced to move further into the asylum, where he is captured by Pighead and is placed in the shotgun collar, which is later used in
Saw III. Still in the trap, Tapp finds a second victim who is being held by Jigsaw. The victim, Jennings Foster, blames Tapp for being in his trap and thus harbors hatred for him. Tapp finds Jennings in a
pendulum trap similar to the one used in
Saw V. Tapp releases Jennings, who quickly runs away, believing that Tapp would get him killed if he stayed with him. Tapp moves on to find the next victim left behind by Jigsaw. He traverses the asylum and is led to the grave of his former partner Detective Sing. It is there that Tapp discovers that Jigsaw has captured Melissa Sing, Detective Sing's widow. She has become a neglectful parent and is convinced that it is Tapp's fault that her husband was killed. Melissa is found in an
iron maiden-esque trap with spinning blades that will mangle her body should the device close on her. Jigsaw informs her that Tapp did not call for backup when searching Jigsaw's lair and that every one of the traps there could have been easily avoided by using standard police procedure, which makes Tapp responsible for his partner's death. After Tapp saves Melissa, she tells him Jigsaw gave her the option to leave Tapp, so she quickly runs away. Tapp is beginning to learn that these people all have a dark connection to him. He proceeds to the offices of the building and finds Oswald McGullicuty in the next Jigsaw trap. Jigsaw felt that Oswald was perverting his message, and so he was placed into a folding table trap, which will snap his body in half if Tapp fails to save him. Tapp saves Oswald, but he is swiftly killed by a compacting metal slab before either have a chance to react. Jigsaw then leads Tapp to the asylum's crematorium, where he informs Tapp that some people actually desire his tests, much to Tapp's surprise. At the crematorium is Obi, an arsonist who had put advertisements in the newspaper seeking for Jigsaw to test him. Tapp saves him from a burning furnace, but Obi is still frustrated because he wanted to survive his own test. Feeling that Tapp is throwing away a gift from Jigsaw, Obi runs away. Tapp then ventures through a theater, where he finds evidence that a former Jigsaw victim is being held there. He soon finds that it is Jeff Ridenhour, the man who was saved by Sing while he and Tapp were in Jigsaw's lair. Jeff has since become suicidal from Tapp's incessant questioning, and has been re-captured by Jigsaw. Tapp saves Jeff from a wall of spikes. Jeff is still frustrated, so he runs away, wounded. As this was the last victim in the asylum, Tapp is free to pursue Jigsaw, but encounters Pighead again. Jigsaw informs Tapp that Pighead wishes to surpass Jigsaw and sabotage Tapp's game, so he must be stopped. Tapp confronts and kills Pighead in order to get a key to proceed, to which Jigsaw rhetorically asks Tapp if he is a murderer.
Finale Tapp heads to the asylum's library, where Jigsaw confronts him in person to present his final choice to conclude his test. Tapp chases Jigsaw, to no avail, but manages to recover the final choice key. At this point, there are two possible endings. Tapp returns to the library, where he must choose between "Freedom", which would simply allow Tapp to leave without catching Jigsaw, and "Truth", in which Jigsaw promises Tapp that his obsession to catch Jigsaw will be satisfied, but at a cost. If the player chooses the
Freedom door, Tapp escapes from the asylum, freeing the rest of the people trapped inside. Tapp returns to his apartment and reviews newspaper clippings which label him a hero by those who survived their tests in the asylum. Despite this, Tapp cannot overcome his obsession with Jigsaw and eventually commits suicide in his apartment, leaving Jigsaw free to conduct the rest of the tests as shown in the rest of the
Saw films. The game's sequel,
Saw II: Flesh & Blood, contains newspaper clippings documenting Tapp's escape and subsequent suicide, confirming that this ending is canon to the franchise. If the player chooses the
Truth door, Tapp pursues a mysterious cloaked figure whom he believes to be Jigsaw. After catching and brutally beating the figure, Tapp realizes that it is actually Melissa Sing. A tape found on Melissa explains that Jigsaw had put her in charge of keeping Tapp alive and making sure he followed the rules of Jigsaw's game after Tapp rescued her. Jigsaw had kidnapped her son and had Pighead sew her mouth shut to avoid her spoiling Tapp's test. Attempting to run away from Tapp, Melissa desperately charges through a nearby door rigged with a shotgun, which kills her in the same way as her late husband, Steven Sing. Tapp suffers a mental breakdown as a result of her death and is placed in a functional asylum where he still believes he is playing Jigsaw's games. ==Development==
