How much blood would you shed to stay alive ?
A young man named Adam (LEIGH WHANNELL) wakes to find himself chained to a rusty pipe inside a decrepit subterranean chamber.
Chained to the opposite side of the room is another bewildered captive, Dr. Lawrence Gordon (CARY ELWES). Between them is a dead man lying in a pool of blood, holding a .38 in his hand. Neither man knows why he has been abducted, but instructions left on a microcassette order Dr. Gordon to kill Adam within eight hours.
If he fails to do so, then both men will die; Dr. Gordon’s wife, Alison (MONICA POTTER), and his daughter will also be killed. Recalling a recent murder investigation by a police detective named Tapp (DANNY GLOVER), Dr. Gordon realizes he and Adam are the next victims of a psychopathic genius known only as ’Jigsaw’.
