Across the room your friends is similary shackled and between you there is part from what looks to have been a human. A video tape goes on with someone calling himself “Jigsaw” who’s greeting you welcome and wondering if you would like to play a game? Obviously you do not have any choice and now there is only 60 minutes to escape the room and solve all the puzzles before the Jigsaw killer releases poisoning gas into the room.
