Two men find themselves trapped in a now deserted public baths; they are chained to the pipes, their only means of escape, a saw and a gun with one bullet. Dr Lawrence and his fellow prisoner are the latest victims of the Jigsaw Killer, a serial murderer who likes to test his prey's humanity as well as their will to survive. Throw in a borderline psychotic cop, unconvincingly played by Glover, a hostage family and some ingeniously gruesome flashbacks and Saw makes for a slightly uninspiring tilt, rather than twist, on the modern horror genre …not as clever as it might have tricked itself into believing.
