"Death is a shortcut (Denmark)" With a dead body laying between them, two men (Whannell and Elwes) wake up in the secure lair of a serial killer who's been nicknamed "Jigsaw" by the police because of his unusual calling card.

"We Dare You Again..." Jigsaw locks a few 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 Jigsaw has set in the shelter lead to death also.
