Who knew the Purge could have been just a big, fun party? Don’t worry, it doesn’t stay happy and non-violent for long, as this first trailer for The First Purge gives a deathly blow by blow of how America’s deadliest holiday came to be.

Amidst a general backdrop of protest and division not unlike our current age, the Purge – a day when laws are unenforced and pent-up violence unleashed – is inaugurated. “Join The First Purge!” comes the voice of the New Founding Fathers of America from a public loudspeaker, while resisters chant “Do Not Purge!”

But the trailer shows the Purge organizers watching in dismay as citizens turn the planned event into some sort of celebration – a turn of events that doesn’t last for long, when soldiers dressed like civilians arrive to stir things up and get people purging.

Says Universal: Behind every tradition lies a revolution. Next Independence Day, witness the rise of our country’s 12 hours of annual lawlessness. Welcome to the movement that began as a simple experiment: The First Purge.

This time around, the cast includes Y’Lan Noel, Lex Scott Davis, Joivan Wade, Luna Lauren Velez and Marisa Tomei.

The First Purge is directed by Gerard McMurray from a screenplay once again by creator James DeMonaco. The film is produced by Platinum Dunes’ Brad Fuller, Andrew Form and Michael Bay, Blumhouse Productions’ Jason Blum and Sébastien K. Lemercier.

Universal takes The First Purge to theaters July 4.
