In 2014, a political party called the "New Founding Fathers of America" are voted into office following an economic collapse and pass a law sanctioning the "Purge," an annual event wherein all crime (including murder) is legal, and emergency services are unavailable for 12 hours. By 2022, the United States is said to have become virtually crime-free, with legal unemployment rates having dropped to 1%

Businessman James Sandin returns to his home in an affluent Los Angeles gated community to wait out the Purge with his wife, Mary, and their children, Zoey and Charlie. The family is assured the security system manufactured by James' company will keep them safe while Zoey meets her boyfriend, Henry. As the year's Purge begins, James enables the security system, and the family disperses to go about their everyday routines. Zoey returns to her room and finds Henry, who had snuck in before the security system was engaged, planning on confronting her father about their relationship. Meanwhile, Charlie watches the security monitors and sees a wounded man calling for help. He temporarily disables the system to allow the man inside, but James races to re-engage the system and holds the man at gunpoint. Henry comes downstairs, points a pistol at James, and opens fire, but James returns fire and mortally wounds Henry. During the chaos, the stranger disappears.

The family sees a gang of masked, heavily armed young people arriving at the front lawn through the surveillance cameras. The leader demands the homeless man, warning that failure to comply will result in an invasion. When Mary asks about the security system, James admits it is incapable of withstanding a determined assault. The family finds and captures the stranger to give him to the gang, only to realize that they would not be better off if they did and choose to defend him and themselves. After the deadline passes, the gang breaks into the house, and James fights back and kills several of them before the leader stabs him. Charlie notices the neighbors leaving their homes on the monitors before the neighbors enter and kill the remaining gang members. Mary is ambushed by two of the Purgers and gets restrained, but the neighbors save her as the Purgers tickle torture her. The leader attempts to kill the family but is killed by Zoey, while James dies from his injuries.

Mary starts to thank the neighbors for saving them, but their leader, Grace Ferrin, reveals her group's hatred for the Sandins due to their wealth being acquired at the neighbors' expense. They capture the Sandins and prepare to kill them, but the stranger returns, kills one of the neighbors, and holds Grace hostage to force them to free the Sandins. Mary stops him from killing the remaining neighbors, not wanting to become a purging monster like them, and decides they will peacefully wait out the remainder of the Purge.

Grace attempts to seize control the following day, but Mary violently breaks her nose with the butt of a shotgun and then smashes her face into a dining table in retaliation, telling her once again no more killing. As sirens sound to signal the end of the Purge, she forces her former friends to leave her house and thanks the stranger for his help. He bids the Sandins luck before leaving as well.

DeMonaco was partially inspired to write the script based on a comment from his wife following a road rage incident. Both DeMonaco and Lemercier recalled initially experiencing negative feedback while seeking funding for their script, being told it was "too un-American" due to its themes of violence and gun control. Jason Blum, representing Universal, was tasked with developing low-cost genre films to the studio, provided DeMonaco and Lemercier with $3 million in funding to produce the film.

The film was shot in Los Angeles.^[11] The relatively low budget of the film resulted in setting the film almost entirely within the house. Hawke slept on Blum's couch during the course of filming and agreed to $10,000 up front for his involvement. Following the film's success, Hawke later made $2 million in backend compensation.^[12][13]
