Jigsaw (2017) Plot Summary & Ending Explained

The film opens with an intense pursuit as police chase after a criminal named Edgar Munsen. After a dramatic crash into police cruisers, Edgar escapes to a rooftop, clutching a trigger while surrounded by officers. He demands the presence of Detective Halloran, who arrives just as the other officers point their guns at Edgar. In a chilling standoff, Edgar insists Halloran must decide who will die; otherwise, he himself will perish. Just as Halloran is about to act, Edgar pulls the trigger, resulting in the cops shooting off his hand and destroying the trigger. Despite Halloran’s attempts to prevent it, another shot rings out, leaving Edgar fatally wounded. In his last breath, he cryptically announces, "the game has begun."

The narrative shifts to a grim chamber where five individuals, including Anna, Carly, Mitch, and Ryan, find themselves shackled to a wall with buckets obscuring their heads. A sinister recording from Jigsaw plays, outlining that in order for them to survive, blood must be shed. As they are dragged inch by inch towards menacing buzz saws, Anna manages to free herself after inflicting a wound on her arm. She urges the others to do likewise, while Carly is unexpectedly attacked from behind. The fifth participant, unaware of the impending danger, is brutally killed.

Meanwhile, a jogger stumbles upon a grisly scene—a corpse hanging from a bridge, head covered with a bucket. This discovery leads to the morgue, where forensic pathologists Logan Nelson and Eleanor Bonneville examine the remains, quickly joined by Halloran and his partner Detective Hunt. They uncover horrific clues: the victim's head has been severed and a chunk of flesh, cut into a jigsaw shape, is missing. A recording hidden in the corpse’s neck eerily states, "now there are only four left."

The remaining victims are transported to a barn where their chains continue to threaten their survival. As tensions escalate, they discover that one among them—Carly—holds a grim secret of theft that links her to an innocent life lost. In a frantic test orchestrated by Jigsaw, they are forced to choose between an antidote and two lethal alternatives. Carly's refusal to act leads to a horrific demise when Ryan injects her with all three solutions, resulting in agonizing death while freeing himself and the others.

Detective Halloran’s investigation reveals further horrors, including a woman whose face has been ravaged by acid. As the plot deepens, the remaining three participants confront the burden of their past transgressions, leading to a series of harrowing trials and confessions that culminate in acts of betrayal and sacrifice. In a moment of desperation, Ryan’s attempt to escape results in severe injury, while Anna and Mitch fight for survival against a cascade of pointed obstacles.

The tension escalates with the reappearance of Edgar, who has vanished under mysterious circumstances. Desperate for answers, Halloran initiates a search for Jigsaw’s grave only to find Edgar’s body instead. This revelation hints that Jigsaw’s intricate web of deceit is far more convoluted than initially understood.

As Logan and Eleanor dig deeper into the disturbing legacy of Jigsaw, they uncover sinister motives tied to Halloran's actions, which now seem suspect. In a gripping turn of fate, the audience views the ultimate downfall of each character, where Mitch's life hangs in the balance while Anna and Ryan grapple with the twisted morality of their past decisions.

Eventually, the film reaches its climax in a basement where Halloran and Logan are ensnared with devices rigged to kill. With a final recording, they face an agonizing choice that tests their morality. As the laser devices activate, Logan’s haunting confession reveals his tragic mistake that altered lives forever. Halloran is left to confront the damning truth of his profession—a final betrayal that propels him toward a gruesome fate.

In a shocking twist, the orchestrator of these harrowing scenarios reveals his real identity and the motivation behind them. As Halloran meets his grisly end, Logan emerges as the newest bearer of Jigsaw's dreadful legacy. With a chilling declaration, he pronounces, "I speak for the dead," leaving the narrative wrapped in darkness, duplicity, and moral reckoning.

The ending of Jigsaw reveals complex twists that deepen the story of the infamous Jigsaw killer. The film is told through two timelines: one set in the past, before John Kramer's death, and another in the present, a decade after his demise. In what appears to be a continuation of Kramer's philosophy, the story unveils that the farm sequence, which features a series of deadly traps, was actually Jigsaw’s very first game. This was his attempt to reenact his own retribution and to reflect on the importance of appreciating life, targeting flawed individuals who had committed sins. These victims were chosen because they had avoided facing the consequences of their actions. The farm was owned by Kramer’s wife, who was later killed in the series, linking Kramer's personal history to his deadly pursuits.

The twist about John Kramer's return is that he’s alive and actively orchestrating the new game himself, contradicting what was previously thought—that he had died. The film also reveals a second major twist concerning the real identity of the copycat killer. It turns out that Logan Nelson, a hospital pathologist and Kramer’s former apprentice, is actually the mastermind behind the revived Jigsaw. Logan’s motivation was revenge on Detective Halloran, who had previously let murders slip away and was responsible for his wife’s death. Logan meticulously recreated Kramer's early traps and used doctored evidence to frame Halloran, aiming to enact his own form of justice by recreating the original game and getting revenge.
