"Spiral: From the Book of Saw" is a 2021 American horror film directed by Darren Lynn Bousman and written by Josh Stolberg and Peter Goldfinger. It serves as the ninth installment in the "Saw" film series and acts as a spin-off rather than a direct sequel to the previous films.
In "Spiral," a new killer emerges who targets corrupt cops and subjects them to Jigsaw-style traps. As the bodies pile up, Detective Ezekiel "Zeke" Banks (played by Chris Rock) and his rookie partner William Schenk (played by Max Minghella) are drawn into the investigation. Banks, who has a complicated history with the police department, finds himself at the center of the killer's twisted game.
As Banks and Schenk race against time to catch the killer and uncover the truth behind the murders, they must confront their own demons and navigate a web of corruption and deceit within the police department.
"Spiral: From the Book of Saw" received mixed to positive reviews from critics, with praise for Chris Rock's performance and the film's attempts to inject new life into the franchise. However, some critics found fault with the film's pacing and predictability. Despite mixed reviews, the film was a modest commercial success, grossing over $37 million worldwide. It signaled a new direction for the "Saw" franchise and left the door open for potential future installments.
