The Purge: Anarchy (2014)

In 2023, as people across America prepare for the annual Purge, where all crimes are legalized, an anti-Purge resistance group formed by Carmelo Johns hacks into live feeds to denounce the NFFA.

In L.A., waitress Eva Sanchez returns home to her daughter Cali and terminally ill father Rico. As Eva and Cali prepare to barricade themselves, Rico slips out to a waiting limousine. He has offered to be killed by a wealthy family in exchange for money paid to Eva and Cali. Meanwhile, estranged married couple Shane and Liz visit a grocery store, only to be harassed by a masked gang of skateboarders and dirt bikers. Their car breaks down after being tampered with by the biker gang.

Off-duty LAPD sergeant Leo Barnes plots to kill Warren Grass. The day before the previous year's Purge, Warren struck Leo's son Nicholas while driving drunk, but was acquitted due to Nicholas dying on Purge night. Ignoring his ex-wife Janice's pleas, Leo loads up and drives out into the streets.

As Liz and Shane try to find safer hiding places, the Purge commences. Eva and Cali notice NFFA paramilitary amassing in the street below, and the superintendent, Diego, enters her apartment. Diego is gunned down by a paramilitary platoon, which captures the women to offer them to their leader, Big Daddy. Leo passes by and rescues Eva and Cali after killing the troops and wounding Big Daddy. They find Shane and Liz hiding in Leo's car. The group flees just as Big Daddy fires at them. After Leo's car breaks down, the group flees on foot.

As the group navigates the hostile streets, they find a paramilitary van surrounded by soldiers who were shot by the resistance fighters. After freeing Shane from a trap and taking guns from the abandoned truck, they head to the subways. They pass by a harmless homeless encampment, but soon after, find themselves being chased by a rampaging Pyrotechnic purging gang that invades the subway and sets the tunnel ablaze. Shane is wounded, but the group manages to escape after he and Liz destroy the gang's all-terrain vehicle and its propane tank with the salvaged guns.

The group returns to the streets, but as they near Eva’s friend Tanya's apartment building, Eva unknowingly signals a traffic camera to identify them to the paramilitary troops. They reach Tanya's house, and Tanya's family takes them in. However, Tanya's sister Lorraine murders her sister for sleeping with her husband. The group leaves the family, only to be captured by the masked gang who ambushed Shane and Liz earlier. The gang sells them to an auction, taking them to a theater where upper-class Purgers bid on them for human hunting.

After the group is forced into the arena, Leo subdues and kills a Purger, taking his weapon and night vision device, overpowering and killing several other attackers, before the head Purger calls in security. Shane is shot and killed by security forces just before the anti-Purge group attacks the compound, killing the security forces and remaining Purgers; Liz chooses to stay with the resistance fighters while Leo, Eva, and Cali leave. Leo steals a car and drives off with Eva and Cali, heading for Warren Grass.

Despite Eva and Cali's pleas to abandon his revenge plans, Leo enters the house to confront Warren. As Leo exits the house, he is shot by Big Daddy, who reveals that the NFFA secretly dispatches death squads to increase the body count because the Purge has been eliminating too few people of the lower class. Just as Big Daddy is about to kill Leo, Warren kills Big Daddy, revealing that Leo chose to forgive and spare him. Just as Big Daddy's death squad appears and Eva, Cali, and Warren prepare to defend themselves, sirens blare to signal the end of the Purge (making Big Daddy's death legal and sparing Leo). Warren takes Eva, Cali, and Leo to the hospital as news and police helicopters fly over the city.
