'The Purge: Anarchy' Trailer Debuts: Watch It Now

'Captain America' star Frank Grillo cuts through the chaos in the first trailer for the 'Purge' sequel.

Some do it for fun. Some just try to survive. No matter the reason, the inevitability remains: there's a new "Purge" on the way.

The first trailer for "The Purge: Anarchy" has arrived online, bringing fans of the first "Purge" film their newest look at what happens to America when all crime is legalized for 12 hours once a year. Written and directed by James DeMonaco, the new "Purge" leaves behind the characters played by Ethan Hawke and Lena Headey, and focuses instead on a grander night of crime.

"Captain America: The Winter Soldier" actor Frank Grillo steps into the spotlight for "Anarchy," on a vengeance quest that isn't entirely explained in the trailer. Whatever Grillo's motivations are, it appears he has a soft side, as well. When a couple's car breaks down, leaving them vulnerable to the 12-hour free-fall of civilization, Grillo's character stops and helps them through the rest of the night.

"As long as we keep moving," he tells them, "we're going to be okay."

That's a bold statement to make, given the absolute pandemonium ringing throughout the crime-ravaged streets. Killers in masks run rampant, auctions are held for the social elite to bid on sin — all in all, it's an utter nightmare for anyone unlucky enough to be out and exposed to the whims of anarchy.

"The Purge: Anarchy" wreaks havoc nationwide on July 18.
