Two men (Cary Elwes and Leigh Whannell) wake up chained by
the foot to pipes on opposite sides of a decrepit subterranean room. Between
them, lying face down in a pool of blood is a dead man with a gun in his hand.
Instructions left on a tape player order one of them to kill the other within
eight hours. If he fails to do so, he will be killed along with his family and
his cellmate. The only escape tools the men have are two handsaws -- too weak to
cut their steel chains but capable of cutting through flesh and bone. Also with
Danny Glover, Leigh Whannell, Monica Potter and Michael Emerson. Directed by
James Wan. [1:40 - R]
