As Jigsaw reveals himself to Adam (as seen in the first Saw), Dr. Gordon crawls from the bathroom to 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.
