Adam, a photographer, awakens in a bathtub along with Dr. Lawrence, an oncologist, who turns on the lights. Both men are chained at the ankle to pipes at opposite ends of the room. Lying between them is a corpse in a small pool of blood holding a revolver and a microcassette recorder.
Adam and Lawrence discover tapes in their pockets, and Adam manages to take the tape recorder. Adam finds out that he must escape the bathroom, while Lawrence must kill Adam before six o'clock, or his wife Allison and daughter Diana will be killed and he will be left to rot. They also learn that the corpse was another victim who shot himself before he could succumb to a deadly poison in his blood. Using clues, Adam finds a bag in the toilet, containing two hacksaws, though neither is able to cut through the chains. Lawrence realizes that the saws are not meant for their chains, but for their feet, and tells Adam that they have been captured by the Jigsaw Killer. Dr. Gordon was then approached by Detectives David Tapp and Steven Sing about his penlight being found at the scene of a Jigsaw game. He viewed the testimony of Amanda, a heroin addict and the only known survivor of Jigsaw's games, who believes that Jigsaw helped her.
Other Jigsaw victims include Paul, who was trapped in a cage filled with razor wire, and Mark, who had to obtain an antidote for the poison in his body from a safe, the combination scrambled on the room's walls, with only a candle for light while himself being covered in a flammable substance and having to walk over broken glass.
Zep moves to kill Diana and Alison, but Alison manages to overpower him. However, as Alison speaks to Lawrence on the phone, Zep attacks her and the gunshots from the struggle get Tapp's attention. Lawrence, who only hears gunshots and screaming, is electrocuted and loses reach of the phone.
