Jigsaw (Tobin Bell) and his apprentice Amanda (Shawnee Smith) are dead. Upon the news of Detective Kerry (Dina Meyer)'s murder, two seasoned FBI profilers, Agent Strahm (Scott Patterson) and Agent Perez (Athena Karkanis), arrive at the depleted police precinct and help veteran Detective Hoffman (Costas Mandylor) sift through Jigsaw's latest grisly game of victims and piece together the puzzle. However, when SWAT Commander Rigg (Lyriq Bent), the last officer untouched by Jigsaw, is suddenly abducted and thrust into the madman's harrowing game, the officer has but ninety minutes to overcome a series of interconnected traps... or face the deadly consequences. Rigg's citywide pursuit leaves a wake of dead bodies, and Detective Hoffman and the FBI uncover long hidden clues that lead them back to Jigsaw's ex-wife Jill (Betsy Russell). The genesis of Jigsaw's evil is unveiled, exposing the puppet master's true intentions and the sinister plan for his past, present and future victims.
