Rigg and Strahm arrive separately at the Gideon Meatpacking Plant. As Rigg goes in search of Matthews and Hoffman, Strahm trails Jeff Denlon, who is looking for his wife Lynn and daughter Corbett. With just a minute left on the countdown, Rigg finds the room holding Matthews and Hoffman and prepares to open the door, ignoring the message that instructs him to wait. Matthews, knowing that he will die if the door is opened before the time is up, shoots Rigg through the glass in the door. With one minute left, Rigg bursts into the room, which triggers two huge blocks of ice that come crashing down on Matthews' head, killing him. Rigg then shoots Art, thinking he is the one responsible for the traps. Meanwhile, Strahm chases Jeff into the operating room (shown at the end of Saw III). He shoots Jeff, who attacks him while screaming, "Where is my daughter?" Jigsaw can be seen lying on the operating table with his throat cut. Lynn's headless body and Amanda's bloody body can be seen lying on the floor. Rigg finds a tape that details the rules of the game and how he violated them and that, if he had not entered the room before the time was up, Matthews and Hoffman would have lived. As Rigg tries to crawl to his feet, Hoffman releases himself from the chair and says "Game over", revealing that he is in fact Jigsaw's other accomplice. This matches the FBI's theory that Jigsaw a.) had more than one accomplice and b.) one of those accomplices was a cop involved with the case. He then goes to the operating room and locks the door, leaving Strahm inside with the bodies of Jigsaw, Amanda, Lynn, and Jeff. In the final scene, Jigsaw's voice on the tape recovered from his stomach can be heard, warning that the games are not over just because he is dead, and that "you will not walk away untested".
