The Purge (2013)

In 2022, the United States of America celebrates once a year "The Purge", a 12-hour period when any crime is allowed including murder. The result is economical growth and a society free of homeless, sick and unproductive persons. James Sandin is a successful salesman that sells security systems for houses. He lives with his wife Mary and his teenage son Charlie and daughter Zoey in a fancy house in the suburb. During the purge, James seals his house and plans to watch a movie with his family. However, Charlie sees a stranger fleeing from a group that is hunting him down and he disarms the security device and lets the man in. But the leader of the group gives an ultimatum to James: if he does not deliver the man to the group, they would kill the whole family. Now James has to find where the man is hidden and decide his fate.
