A man emerges from nowhere claiming he is one of the few to have survived a 'Jigsaw trap' and his self-written book on the experience becomes a best-seller. However, his claim is dismissed by the doctor who survived the ankle-trap in the first movie and as punishment he is submitted to a real trap in which he has to free several people connected to his claim which would ultimately lead him to one final challenge: to free his wife from the final trap before the clock runs out.

The seventh - and supposedly last - in the Saw franchise is one of the most gorriest, and one of the dullest. Tobin Bell's appearence in the film is incredibly minimal, despite his top billing.
