This movie may not explore that entirely, but The Purge: The Island will at least explain why people were willing to stick around for this first experimental night of violence.
Series creator James DeMonaco has now officially confirmed that the upcoming fourth entry, which is going to be a prequel, is officially titled The Purge: The Island, while also revealing the first official plot details.
He revealed that this movie will tell the story of the first ever experimental Purge night, which is going to take place on Staten Island.
After the third movie, The Purge: Election Year, some elements of the series started to feel a bit tired.
