Saw II: Jigsaw is back and this time he has locked some very unlucky people in a booby trapped shelter. They must find a way out before they inhale too much of a lethal nerve gas and die.

But when the news of Detective Kerry's murder becomes public, two seasoned FBI profilers, Agent Strahm and Agent Perez, arrive in the terrified community. There, they assist veteran Detective Hoffman in sifting through Jigsaw's latest grisly remains and piecing together the puzzle.
