The purge

Another day were in tatiana's house with my friends and we watched The purge and we were very scared. 

This film is about United States in 2022 where the government have instituted an anual night called "the purge" during witch all criminal activity becomes legal. When the purge begins, everyone closes at home with his family safe. The protagonists are a family of four, parents, a daughter and a younger son. During the purge, the youngest son Charlie opens the door to a black guy who needs help because other people want to kill him. Then the murderers tell at family they have two options, either deliver the boy to come in and die or kill everyone. The father wants to give the boy to protect his family but others will not, and ultimately don't deliver the boy and choose to fight against all murderers.
