Meanwhile, Laura succumbs to the nerve agent, having been more affected than the others. Desperate to get his hands on the antidote, he kills Jonas in a fight and begins to hunt down the others. Thereby, he realizes that each one of them has one number of the combination to the safe written on their necks. In the house, Xavier returns to the first room where they initially woke up and discovers a colored number written in the back of Gus' neck. Furthermore, he warns him that Daniel's life will be endangered once the other prisoners learn about his connection to Eric. John however remains barely impressed and reveals that all of the victims in the house, except for Daniel, have all been innocently framed by Eric for various crimes they didn't commit. At Kerry's suggestion, Eric tries to provoke John by destroying several of his documents and sketches around the area. As he explains his moral ideals to Eric, the tech team finally arrives. With the time he has left, he hopes to inspire the same appreciation in others by testing their will to live. He eventually talks about his cancer diagnosis and his failed suicide attempt where he survived and found a new appreciation for his life. Meanwhile, John passes the two hours with both idle and cryptic conversation with an increasingly frustrated Eric. While she manages to obtain the key, Xavier fails to unlock the door in time and subsequently abandons the group out of frustration. However, instead of accomplishing his task himself, he throws Amanda into the pit. This test is meant for Xavier, who is a drug dealer. Another tape tells them that the next antidote is hidden behind a steel door and the key to open it lies somewhere in a pit filled with thousands of used syringes. As the remaining prisoners continue to search the house, Jonas leads them to another room upstairs. Pressured by Xavier, Obi crawls into a furnace to retrieve two of the antidotes, but inadvertently activates the oven and is burned alive. Following his death, the group makes their way to the basement, where another tape reveals that Obi helped Jigsaw to abduct the others. Xavier refuses to heed the warning and uses the key, thereby causing Gus to be shot by a booby trap connected to the lock. Besides the tape, the prisoners also find a key and a warning message, which tells them not to use the key to open the door of the room. The combination is said to be "in the back of their minds" and the order, in which they have to be programmed in, is found "over the rainbow". One antidote is in a safe in the room where they all initially woke up. The eight victims in the house - Daniel, Amanda, Xavier Chavez, Jonas Singer, Addison Corday, Laura Hunter, Obi Tate, and Gus Colyard - are informed about the nerve agent as well as the antidotes by an audio tape left by Jigsaw. Pressured by Kerry, Eric reluctantly agrees to John's ultimatum in order to buy time for the police tech team to arrive and track the signal from the video feed. John assures Eric that he will see his son again in a "safe and secure state" if he agrees to talk with him alone until the two hours are over.

While being trapped there, they breathe in a deadly nerve agent and have two hours to find syringes with the antidote, which are hidden all around the house. On these monitors, Eric and the others witness eight people, including Daniel Matthews, Eric's son, and Amanda Young, the only known survivor of one of John's games, who are all trapped inside a big house. However, as the officers are about to arrest him, John reveals that he has already planned to be found by them and shows them a set of surveillance monitors. Upon doing so, they find the killer, John Kramer, who is severely weakened by his cancer disease. Initially reluctant to become involved in the investigation, Eric quickly manages to locate Jigsaw's hideout at the abandoned Wilson Steel Plant and therefore decides to join Kerry and Sergeant Daniel Rigg as they raid the plant with a SWAT team. When Michael's corpse is found shortly afterwards, his employer, Detective Eric Matthews, is called to the crime scene by Detective Allison Kerry when she discovers a message for him left by the Jigsaw Killer. Michael, however, cannot bring himself to cut out his eye and is killed when the mask closes on his head. A videotape informs him that he has one minute to retrieve the key from behind his right eye with a scalpel. Michael Marks, a police informant, wakes up and finds himself with a spike-filled mask locked around his neck.
