Saw VI

Predatory lenders Eddie and Simone, locked in head harnesses with screws aimed at their temples, have one minute to each carve flesh from their bodies with their provided cutting tools and weigh the scale individually in favor for survival. When the overweight Eddie slices chunks of fat from his stomach, the contraption kills him after Simone chops off her arm and tips the scale until the timer expires. Their game is observed by Mark Hoffman, who had just escaped from the trap that killed FBI Agent Peter Strahm. He then uses Strahm's severed hand to plant his fingerprints at the scene. The police and FBI Agent Dan Erickson investigate alongside FBI Agent Lindsey Perez, whose survival was concealed by Erickson for her protection. During Eddie's autopsy, Dr. Adam Heffner reveals the scalpel used to cut the flesh pieces from his body is the same blade used years ago on Seth Baxter. Perez and Erickson reopen the investigation to analyze the videotape found at the crime scene and distort the speaker's voice.
