The movie Jigsaw is the eighth installment in the Saw franchise. It starts off with a new series of gruesome and puzzling deaths occurring in the city, which appears to be the work of the notorious John Kramer, also known as the Jigsaw killer. The murders lead the police to start an investigation, where they find evidence linking Kramer to the crimes.
However, there is one problem - John Kramer has been dead for over a decade, having died in a previous Saw film. This leads the police and FBI to question whether there is a copycat killer on the loose or whether Kramer is somehow still alive.
As the investigation progresses, it becomes clear that Kramer's legacy continues to live on. A new group of victims, including five strangers caught in a twisted game of survival, must face a series of deadly traps set up by Jigsaw. The group must work together to see if they can survive the game and uncover the truth behind the killings.
Throughout the movie, there are flashbacks to previous Saw movies, offering more insight into Kramer's original motives and modus operandi. As the movie draws to a close, the truth about the new Jigsaw's identity is uncovered, revealing a shocking twist that takes the franchise in a new direction.
