Description：The murderous Jigsaw (Tobin Bell) is back with a newer and more bizarre killing game. Another victim with the “Jigsaw” signature death features is discovered by the police, which brings Agent Eric Matthews (Donnie Wahlberg) back to his previous horror nightmare. But unexpectedly, the killer left very obvious clues, and the police's investigation and evidence collection went very smoothly. In fact, all of this is under the control of “Jigsaw” (Tobin Bell). Leaving clues and getting himself arrested are the important prerequisites for him to play the next evil game: 8 strangers will be forced to join the game, and what's even crazier is that another player besides him has been identified as Matthews. Under the planning of “Jigsaw”, another thrilling game of life and death is about to begin.
