The Purge is a high-concept home invasion thriller set in a supposedly Utopian future America, in which citizens are allowed one night per year to commit any crime they want, penalty-free. Needless to say, that doesn't work out so well for a wealthy couple (Ethan Hawke & Lena Headey) when one of their kids lets a desperate stranger hide out in their fortress-like mansion.
The Purge is produced by Jason Blum of Blumhouse Productions (Sinister, Paranormal Activity), with James DeMonaco writing and directing. DeMonaco scripted the 2005 remake of John Carpenter's Assault on Precinct 13, whose plot The Purge strongly resembles. The film is slated for theatrical release on May 31st, and Universal now has a full trailer which you can watch below:
