PTwelve hours, all crime is legal, kill or be killed. The purge is a time when American citizens recognize an evening of lawlessness every year known nationally as Purge Night. During this purge night all emergency services are shut down and all crime is permitted. Those who choose not to purge generally hide in the depth of their excessively safe and locked up houses. A family of four decides to not purge and instead just stay safe. This does not go as planned when their son decides to disarm the security system to let a man on the streets in. To the families surprise he is wanted by a very large group of purgers. When the family decides not to fork him over to the killers all hell breaks loose. 

This is a very suspenseful and thrilling movie. I recommend this film to all looking for a good scary thriller.
