Saw VI Plot Summary and Synopsis
Predatory lenders Eddie and Simone awaken to find their heads locked in harnesses that will drill screws into their temples in 60 seconds. In order to be freed, they’re tasked with carving flesh from their bodies, which they’ll individually weigh in favor for survival. Simone chops off her arm and tips the scale as the timer expires, killing Eddie.
Their game is observed by Mark Hoffman, who has just escaped from the trap that killed FBI Agent Peter Strahm. He uses Strahm’s severed hand to plant his fingerprints at the scene. FBI Agent Dan Erickson leads an investigation into the trap, working alongside Hoffman and FBI Agent Lindsey Perez, Strahm’s former partner, whose survival was concealed by Erickson for her protection.
During Eddie’s autopsy, Dr. Adam Heffner discloses the jigsaw piece carved into his skin doesn’t align with Jigsaw’s modus operandi. Instead, it’s closer to the that of previous victim Seth Baxter, the killer of Hoffman’s sister. Perez and Erickson reopen the investigation into Baxter’s case with the intent to analyze an unknown speaker’s voice in a videotape found at the crime scene.
Hoffman arrives at Jill Tuck’s clinic and demands she hand over the contents of the box her ex-husband John Kramer left her in his will. The contents include five envelopes, each containing information on subjects of Jigsaw’s next game. The primary target is health insurance executive William Easton, whose company’s dubious business policies turned down their sick clients’ coverage for medical treatment, including Kramer’s cancer treatment. After being abducted by Hoffman, William awakens in an abandoned zoo, with bombs strapped to his legs and wrists. He’s suspended in chains alongside the company’s janitor Hank, whose disregard to his own health would prevent him from finding health coverage through William’s company.
The two are hoisted between large metal vises that will crush their bodies each time they take a breath through their oxygen masks. Hank fails the test and is killed, but William is freed and proceeds onward to disarm the remaining explosives and reunite with his family. The second test forces William to choose between saving his elderly secretary Addy or his young file clerk Allen, each hanging from a barbed-wire noose around their neck. Following Allen’s death, William heads to the boiler room, where he unwittingly releases his lawyer Debbie, who must reach the end of a steam maze in order to unlock a speargun strapped to her chest.
Debbie attack William after discovering the key is sewn inside his body, but he manages to stave her off until the timed device pierces her skull. William’s last test finds his six subordinates chained to a rotating roundabout, yet he can only select two to be spared from the blast of a mounted shotgun. They lie, bargain, and argue amongst themselves as William is forced to watch two-thirds of his team succumb to the trap.
Meanwhile, sensationalist journalist Pamela watches William’s game from a closed circuit TV in her own caged paddock. On the opposite side of the enclosure, mother Tara and her teenage son Brent attempt to figure out the purpose of a mysterious lever connected to a vat of hydrofluoric acid. William reaches the end of his path, reuniting with Pamela, who reveals she’s his sister.
He is then confronted by Tara and Brent, who were the family of Harold Abbott, a former client who succumbed to heart disease shortly after William denied his medical coverage. A videotape informs Tara she gets to decide William’s fate by using the lever in her cell. William and Pamela attempt to persuade the Tara to let him live, but an enraged Brent pulls the lever anyway. A platform of needles is released from the ceiling, injecting the acid into William and dissolving his intestines.
During William’s game, Hoffman is called away by Erickson to an audio lab analyzing the Baxter trap’s videotape. When Hoffman’s voice is unscrambled and Strahm’s demise is uncovered, he kills both Erickson and Perez and burns down the lab.
Hoffman returns to the observation room to find the letter he wrote to Amanda Young, which reveals he knew she instigated the robbery at Jill’s clinic that resulted in her miscarriage; Hoffman used this knowledge to blackmail Amanda into killing Dr. Lynn Denlon, failing her final test. The letter was found by Pamela and given to Jill, who ambushes Hoffman. She restrains him and locks a modified Reverse Bear Trap to his head, posthumously fulfilling John’s wish to test Hoffman after his death.
Saw VI Ending
Jill exits the room as Hoffman escapes his wrist restraints. He manages to slip out of the trap after catching it between the bars on the door window right as it springs open, ripping apart his right cheek in the process.
A post credits scene depicts a flashback of Amanda telling Dr. Lynn Denlon’s young daughter not to trust Hoffman.
