What's Elysium, you say? Wikipedia has the premise:
Allegorical, no?In the year 2154, two classes of people exist: the very wealthy, who live on a pristine man-made space station that is disguised as a massive floating city called Elysium, and the rest, who live on an overpopulated, ruined Earth. The people of Earth are desperate to escape the planet’s crime and poverty, and they critically need the state-of-the-art medical care available on Elysium – but some in Elysium will stop at nothing to enforce anti-immigration laws and preserve their citizens’ luxurious lifestyle.
Trailer's awesome, btw. Also, if you hate Matt Damon, you're gonna hate him more.
