Rob Thomas gives the plot of the movie on the Kickstarter page towards the bottom. It could change between then and now, of course, but it seems like a good idea. I'll put it into spoiler tags just in case:
I think it's a good idea. It allows them to bring back a lot of characters and use familar surroundings.
Oh, the campaign is now open to Canadians. Hopefully they can open it up to more international pledges. If that happens, the sky's the limit for how many funds they can raise.
