When some unexpected money comes his way, Carl Black (Mike Epps) moves his family from cold and windy Chicago to bright and sunny Beverly Hills, Calif. As the Blacks settle into their beautiful new home, they start to notice some strange behavior in the neighborhood. Nighttime is approaching, and President El Bama (George Lopez) announces that the annual purge is about to begin. Carl and his loved ones must now endure a 12-hour period of lawlessness before they can enjoy life once again.
