The new dystopian teen movie Divergent could be upping the ante for post-apocalyptic devastation, judging from this brand new trailer. What's happened to Lake Michigan? Find out, in the movie's first full-length trailer.

Divergent, based on Veronica Roth's YA book series, is set in a future Chicago, that's surrounded by a dried-out Lake Michigan and a giant fence. Also in the future, the world will be divided into color-coded factions based on their personality types. Unless you're a Divergent, because that's bad (according to this trailer). Why? We don't know yet — but look, sexy tattoos!
