While investigating the bloody
aftermath of a grizzly murder, Detective Eric Mason (Donnie Wahlberg)
has the feeling that it is the work of Jigsaw, the notorious killer who
disappeared leaving a trail of bodies - and parts - behind.
And Mason is right. Jigsaw is at work again. But instead of two
people locked in a room with only one unthinkable way out, there are
eight. Eight strangers – unaware of their connection to each other --
forced to play out a game that challenges their wits and puts their
lives in jeopardy.
