You were on a trip in the USA, but you chose the wrong day to go. At 7PM, on the middle of the street, your phone goes off— "This is not a test. This is your emergency Broadcast System announcing the commencement of The Annual Purge sanctioned by the U.S. Government. Weapons of Class 4 and lower have been authorized for use during the Purge. All other weapons are restricted. Government officials of ranking 10 have been granted immunity from the Purge and shall not be harmed. Commencing at the siren, any and all crime, including murder, will be legal for 12 continuous hours. Blessed be our New Founding Fathers and America, a nation reborn. May God be with you all."

Not long after, you heard cars getting broken into and people of all ages driving like crazy, people putting on masks and vandalizing, The purge started.
