Saw Review

A photographer named Adam awakens in a dilapidated bathtub, with his ankle chained to a pipe. Across the room is oncologist Dr. Lawrence Gordon, also chained, and between them is the corpse of an apparent suicide victim holding a revolver and a microcassette recorder. Both men find a tape in their pockets, and Adam retrieves the recorder. Adam's tape urges him to survive, while Gordon's tells him to kill Adam by six o'clock or his wife Alison and daughter Diana will be killed. Adam finds a bag containing two hacksaws inside the toilet. Both men try to saw through their chains, but Adam's saw breaks. Gordon realizes that the saws are intended for their feet, and identifies their captor as the Jigsaw Killer, a serial killer testing his victims' will to survive through lethal traps referred to as "games", whom Gordon knows of because he was once a suspect.
