I probably shouldn't even give out this link, but I will... I am forcing myself not to read the review on this, but as you may or may not know, they had a screening of 25 minutes of Final Fantasy VII Advent Children at this film festival. There is a totally detailed description of the event and film here:

It is advertised spoilers, so I'm quite sure most of the plot was revealed and shown here. If you really can't wait go ahead and read, but personally I'm doing a media blackout until the film comes out in Japan and gets fansubbed. Read the review at your own discretion, but I'm telling you here, it probably WILL tell you what happens in Advent Children, whether you see that as a good or bad thing, well hey... That's you.
