As Jigsaw is revealing to Adam to be the mastermind behind all of the "games" (Saw), Dr. Gordon is crawling in the hall outside the bathroom to try and find help. Along the way he reaches a hot pipe and uses it to cauterize his amputated foot. The next scene cuts to an urban shopping area where a crowd of people gather around a storefront window to find two men, Ryan and Brad, tied to a worktable, each with a buzz saw in front of them and their lover, Dina, suspended above. As she is being lowered onto another buzz saw, each of the men must choose to either kill the other person in order to save her, or allow her to die, resulting in their freedom.
Meanwhile, survivors from Jigsaw's previous traps gather to seek the support of self-help guru and fellow survivor Bobby Dagen. Mark Hoffman and Jill Tuck battle over Jigsaw's legacy
