The plot of Saw IV has appeared online, and really it's nothing more than we expected to date. One thing is interesting through, it is a direct continuation, and by direct it looks like it picks up the second the previous one finished.

Here's the plot, and remember if you haven't seen Saw III this might contain hints to a spoiler.

"Jigsaw still haunts the living in Saw IV, forcing them to appreciate life, or face death. As a continuation of Saw III, Jeff must find his daughter and escape the building to which they are confined before they both die. After finding another tape of Jigsaw, Jeff realizes there may be a newly added piece of the puzzle that he must decipher before its too late."

The plot comes from Fearnet through Bloody Disgusting.

I think this is one of the best speculation games we've had in a long time, and I don't know why we're not spending more time discussing it. Where can the story really go from Saw III?

Please note that the comments are more than likely to contain spoilers for Saw III.
