Darren Lynn Bousman takes the helm for this sequel, with The Jigsaw Killer inviting capture by cop Eric Mathews (Donnie Wahlberg).
But once in custody, he reveals his latest puzzle; eight people, including Mathews' son Daniel (Erik Knudsen) are trapped in a derelict house. If they can solve the clues, overcome the murderous traps and work together, they may be able to escape.
If not, the deadly nerve gas that's in the air will kill them all in just two hours.
