"Jigsaw and his apprentice Amanda are dead. Upon "the news of Detective Kerry's murder, two seasoned FBI profilers, Agent Strahm (Scott Patterson) and Agent Perez, arrive at the depleted police precinct and help veteran Detective Hoffman (Costas Mandylor) sift through Jigsaw's latest grizzly game of victims and piece together the puzzle. However, when SWAT Commander Rigg, the last officer untouched by Jigsaw (Tobin Bell), is suddenly abducted and thrust into the madman's harrowing game, the officer has but ninety minutes to overcome a series of interconnected traps...or face the deadly consequences. Rigg's citywide pursuit leaves a wake of dead bodies, and Detective Hoffman and the FBI uncover long hidden clues that lead them back to Jigsaw's ex-wife Jill (Betsy Russell). The genesis of Jigsaw's evil is unveiled, exposing the puppet master's true intentions and the sinister plan for his past, present and future victims."
SAW IV 2007
At the autopsy of the Jigsaw Killer a wax-coated microcassette is found in his stomach, which, when played for Detective Hoffman, promises that 'the games have just begun' and that he 'hopes that he will succeed where others have failed' in his test as he is 'the last man standing.' The next scene takes place in a mausoleum, where Trevor and Art are chained to a large device. Trevor's eyelids have been sewn together, and Art's mouth has been sewn shut, making communication between them impossible. When the device begins pulling them together, they panic, and Art murders Trevor to retrieve a key from his collar. It has been six months since Eric's disappearance, as noted by Detective Hoffman. The police discover the corpse of Detective Kerry, still hanging in the harness of the inescapable trap that killed her in Saw III. After cautioning Lieutenant Rigg for barging through an unsecured door, Hoffman is introduced to FBI Agents Strahm and Perez, who deduce that Amanda Young, Jigsaw's apprentice, would need assistance with Kerry's death, indicating that there is another accomplice to the murder. That evening, Rigg is attacked in his home and Hoffman disappears. When Rigg comes to, a videotape informs him that Detective Matthews is in fact still alive, with ninety minutes to save himself, and that Hoffman's survival is at stake as well. He then undergoes his first test, in which he finds a woman named Brenda. Jigsaw advises Rigg to walk away--to 'see what I see,' as written on the wall--but Rigg's natural instinct to help those in need clouds his judgment. When Rigg removes the pig mask covering Brenda's face, he triggers a trap device that begins to slowly tear her scalp from her head. He succeeds in freeing her, but to his surprise, she comes at him with a knife; Brenda has been told that Rigg is there to arrest her and the only way to stop it is to kill him. He throws her into a mirror and leaves; sometime later, Strahm, Perez, and the police enter the apartment and find that Brenda has died. Rigg's next test is at a motel, where he is instructed to 'feel what I feel,' painted on the door of one room. He must abduct the manager, Ivan, revealed to be a serial rapist. Angered by seeing videos and photos of Ivan's exploits, Rigg forces Ivan into a prearranged trap, which gives him the option between having his limbs savagely ripped off or eyes gouged out. Rigg hands him two controllers that will drive blades into his eyes, blinding him and saving his life. When Ivan runs out of time after blinding only one eye, his limbs are ripped off his body and thrown across the room. Rigg's next test, to 'save as I save,' occurs in a school where Rigg attacked a man acquitted of abusing his family, though Rigg's career was saved by Hoffman. In one of the classrooms, Rigg discovers that same husband and wife impaled together back to back with several long metal rods. The rods are placed such that they pass through vital circulatory points of his body, but non-vital points of hers. If she has the courage to remove the rods, her abusive husband will bleed to death but she will survive. By the time Rigg finds the couple, she has pulled out all but one rod and gone into shock; she suddenly wakes up and Rigg tells her that she has to save herself. He removes the last spike, wraps his jacket around her, hands her the key to the harness she and her husband are strapped into, and sets off a fire alarm to alert emergency services to her position, then leaves. Strahm and Perez arrive on the scene, having previously realized that they have both become targets in this latest series of games. They determine that all of the victims were defended by Art, who is also the lawyer of Jill Tuck, John Kramer's ex-wife. A trap meant for the woman, (had Rigg interfered with the trap) fires a spear through a photographer and kills her on the scene. Perez finds Billy, Jigsaw's puppet, in the office. She is told via tape recorder that Strahm will 'soon take the life of an innocent man' and that her 'next step is critical.' Ignoring the warning, she takes a closer look at Billy, whose face suddenly explodes and showers her with shrapnel; she is rushed to the hospital in critical condition due to shards sticking out of her face. Furious, Strahm interrogates Jill, who recounts Jigsaw's backstory. She was once pregnant with a boy to be named Gideon (after John's first store), but the baby was lost when Cecil Adams robbed the clinic at which she was employed and he slammed a door into her stomach, causing a mis-carriage. She and her husband grew apart and divorced. After learning that he had cancer and only a short while to live, John kidnaps Cecil and places him in a trap, the first trap he ever built. Cecil must push his face against several knives in order to release his wrists, which have been slit due to razor blades in the arms of the chair He begins to do so, but the chair collapses before he can reach the release switch. Noticing John standing in front of him watching, Cecil, in his anger, lunges at John to kill him, but falls into a mesh of barbed wire as John moves aside at the last second. Strahm makes connections from Jill's story to the Gideon Meat Factory, the scene of Rigg's final test. Strahm arrives but finds himself lost, accidentally trailing Jeff Reinhart - making the viewers believe Jeff is looking for his daughter. In reality, however, the events of this film and Saw III are now unfolding at the same time. Rigg, meanwhile, approaches his final test. In the next room are Art, Matthews, and Hoffman; Matthews stands on an ice block with a chain-noose cinched around his neck, while Hoffman is strapped into a chair with an electrode by his feet. They are at opposite ends of a balanced seesaw, but if Matthews slips off the ice or too much of it melts, he will be hanged and the weight shift will dump the runoff water onto Hoffman's end, electrocuting him. All three men find out that if the door is opened before the ninety-minute period for Rigg's tests runs out, Matthews' head will be crushed between two ice blocks and Hoffman will die with him. Rigg appears on the other side of the door, Matthews attempts to shout Rigg away, however when Rigg persists in trying to enter, Matthews in desperation shoots at Rigg through the door, using a gun given to him by Art. Following the shot, which hit him in the stomach, Rigg lunges through the door with 1 second to spare. This causes the mechanism holding the two ice blocks above Matthews to start, the blocks swing down obliterating Matthews' head in the process. Rigg shoots and kills Art, mistaking the tape recorder in his hand for a gun, and plays the tape only to discover that he has failed his final test. Rigg's test was to learn that he cannot save everyone, a test he would have passed if he had allowed the time limit to expire. Also Hoffman had warned him earlier in the film not to barge into unsecured doors. Elsewhere, Strahm faces off with Jeff in the makeshift sickroom from Saw III. Jeff waves a gun at Strahm, believing him to be involved in the abduction of his daughter; Strahm kills Jeff in self-defense. Hoffman releases himself from his chair unharmed, revealing himself to be Jigsaw's apprentice, and seals an injured Rigg and a bewildered Strahm in the factory.
