This is not for the weakhearted.
In the new film "Purge," Americans are given 12 hours per year where all crime is legal and all emergency services are put on hold. Basically, it's anarchy, but crime falls and so does unemployment.
Naturally, a lot goes wrong, but the trailer is pretty interesting.
Take a look, but be warned: Trailer for this R-rated film is intense and does contain disturbing content.
