The Forever Purge is the 5th installment in the "The Purge" Series. If you are familiar with the Purge films then you will know that in this universe there are new Founding Fathers who enacted one day per year were all crime is legal from 7pm-7am. So people put on mask and go out and rob and kill for 12 hours and cannot be arrested or charge for crimes. In this film, a group decides they are tired of their rights being infringed upon and tired of illegal aliens taking their jobs and so the day after the "The Purge", they decide to have a "Forever Purge" to take back their country. They are in pretty much all 50 states and continue to attack and kill anyone who isn't part of their cause. The film centers around a family of White Ranchers who employ Mexicans and they must all band together to get everyone out alive.
So these films are very politically charged and it very clear who they are targeting with "The Forever Purge". They are most likely the same group of people who stormed the Capital on January 6th, 2021, but of course, a lot more organized. There is lots of violence and killing in this film and it was pretty entertaining. While it wasn't the best Purge film, it was definitely good.
