Jigsaw locks 8 or 9 unlucky people in a booby trapped shelter and they must find a way out before they inhale too much of a lethal nerve gas and die. But they must watch out, for the traps that the Jigsaw has set in the shelter lead to death also.

We dare you again... Jigsaw is back. The brilliant, but disturbed mastermind who wreaked havoc on his victims in last year's Saw is back for another round of horrifying life-or-death games...
