Saw IV (Unrated) (DVD)

Jigsaw and his apprentice Amanda are dead. Upon the news of Detective Kerry's murder, two seasoned FBI profilers, Agent Strahm (Scott Patterson) and Agent Perez, arrive at the depleted police precinct and help veteran Detective Hoffman (Costas Mandylor) sift through Jigsaw's latest grizzly game of victims and piece together the puzzle. However, when SWAT Commander Rigg, the last officer untouched by Jigsaw (Tobin Bell), 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.
