Saw IV Review

An autopsy of the Jigsaw Killer reveals a wax-coated microcassette in his stomach. The tape shows Detective Hoffman promising that "the games have just begun." In a mausoleum, Trevor and Art are chained to a large device. Trevor's eyes have been sewn shut, and Art's mouth has been sewn shut, making communication between them impossible. When the device begins pulling them together, they panic, and Art murders Trevor to retrieve a key from his collar.
