Saw - Lawrence Gordon’s Foot Cut

Adam Stanehight and Doctor Lawrence Gordon both awake in some abandoned underground based bathroom. Both men are chanied at their ankles to pipes in opposite corners of the room. Lying between the two prisoners is a corpse who has shot himself in the head, clutching a revolver in one hand and a cassette player in the other. After retrieving the cassette player, Lawrence plays a cassette tape left for him in which John reveals that if he fails to kill Adam by six o’clock he and his family will die.
