Universal Pictures is set to release The Purge on May 31st, and the first trailer has just been released. The movie stars Ethan Hawke in a unique home invasion scenario where the government sanctions an annual 12-hour window when all criminal activity becomes legal:

"If on one night every year, you could commit any crime without facing consequences, what would you do? In The Purge, a speculative thriller that follows one family over the course of a single night, four people will be tested to see how far they will go to protect themselves when the vicious outside world breaks into their home. In an America wracked by crime and overcrowded prisons, the government has sanctioned an annual 12-hour period in which any and all criminal activity—including murder—becomes legal. The police can't be called. Hospitals suspend help. It's one night when the citizenry regulates itself without thought of punishment. On this night plagued by violence and an epidemic of crime, one family wrestles with the decision of who they will become when a stranger comes knocking."

The Purge was directed by James DeMonaco, written by James DeMonaco, and stars Ethan Hawke, Lena Headey, Adelaide Kane, and Max Burkholder.
