Saw II Review

Police informant Michael awakens in a room with a spike-filled mask locked around his neck. He refuses to retrieve the key from his eye and is killed when the mask closes on his head. At the scene of Michael's murder, Detective Kerry finds a message for her former partner, Detective Eric Matthews. Matthews joins Kerry and Officer Rigg in leading a SWAT team to the factory which produced the lock from Michael's trap. There they apprehend John Kramer, the Jigsaw Killer, who indicates computer monitors showing eight people trapped in a house, including his only known survivor Amanda, Matthews' son Daniel, and six other victims: Xavier, Jonas, Laura, Addison, Obi, and Gus. A nerve agent filling the house will kill them all within two hours, but John assures Matthews that if he follows the rules of his own game, he will see Daniel again. At Kerry's urging, Matthews agrees to buy time for the tech team to arrive and trace the video signal. During their conversation, John reveals to Matthews that his main motivation for his games was a suicide attempt after his cancer diagnosis, which led to a newfound appreciation for life; the games are intended to help his victims develop the same appreciation.
