The relevant plot points of the film (chaotic and complex though it is!) gradually creep out through the dialogue, so most of it comes together if you hang on in there. I guess all you can do is suck it and see if it grabs you XD

Or you could always read the crack_van summary here (http://community.livejournal.com/crack_van/1441097.html?style=mine), but somehow trying to summarise it just makes it sound even more mad!
