Five individuals awaken to find themselves with metal, bucket-like devices on their heads and chained to a wall. Jigsaw's voice tells them that they have to admit their sins or else they'll be punished. Right away one of them is killed-and the rest are dragged, via the chains, into different rooms to suffer different tortures. Meanwhile, a detective and a coroner speculate on what's going on and if Jigsaw is back torturing people.
There are some extremely gory death scenes, as with all the SAW movies. This time, I didn't find any of the "victims" sympathetic, which I thought interesting. This isn't the best or most intense SAW movie but it is one that continues to add to the storyline of the series. I didn't quite see that "twist" at the end-and it makes a lot of sense in explaining how John Kramer, aka "Jigsaw" and still be doing this beyond the grave. Recommended.
