In the grimy underbelly of a sprawling urban decay, the nefarious legacy of the once-feared Jigsaw killer lingers like a ghost in the machine. A series of gruesome crimes baffles the police, each marked by the diabolical ingenuity that echoes Jigsaw’s twisted moral paradigm. As fear grips a city terrorized by the specter of these copycat crimes, a determined detective, whose past is marred by a haunting encounter with the original Jigsaw, is hell-bent on uncovering the truth. She senses that the key to solving the blood-soaked puzzle lies within the deranged philosophy of the original mastermind, and she may need to delve into that dark psyche to stop the carnage.

Amidst the backdrop of psychological terror, a group of strangers awakens to find themselves trapped in an elaborate and merciless game of survival. The rules are simple yet savagely complex: navigate the treacherous path laid out by their unseen captor or face the deadly consequences of failure. As the clock ticks and the bodies begin to pile up, alliances form while paranoia festers, blurring the line between victim and perpetrator. Each person is connected by a thread of secrets, but unraveling them could be the difference between life and ghastly demise. With a pathogen of fear spreading through the city above and the shadow of Jigsaw's influence ever-present, they must confront their own dark histories to find redemption—or meet a fate carefully orchestrated by a new architect of misery.
