John Kramer, known as Jigsaw, places two men - a photographer named Adam and Dr. Lawrence Gordon - in a trapped room and forces them to participate in deadly games. If Gordon fails to kill Adam by 6pm, Jigsaw threatens Gordon's family. The police investigate Jigsaw's crimes and track him to a warehouse, but he escapes after injuring two officers. It's revealed that Gordon must cut off his own foot to survive, and he shoots Adam, only to learn he completed the game too late - the dead body in the room was Jigsaw in disguise.
