Highlights
The annual Purge is announced for Connecticut, lasting 12 hours from 6 p.m. on December 5th to 6 a.m. on December 6th, 2029. All laws are suspended, crimes are tolerated, and there will be no prosecution. Emergency services will be non-functional, and electricity will be cut off. Teenagers Riley, Jenna, Tyler, and Jake react to the terrifying news, with Riley's parents trapped outside the state. Tyler reveals he has been preparing for this for months, having researched home security and barricading, while Jake's family considers fleeing to Massachusetts.
A neighborhood chat among adults reveals mixed reactions. Damian Kaine suggests forming a neighborhood defense, while Derek offers hunting rifles. Dr. Patricia Hayes emphasizes medical preparedness for casualties. Damian proposes a small, trusted group for defense, cautioning against larger groups due to infiltration risks. The conversation quickly shifts from defense to offense, with some members expressing a willingness to take proactive measures against perceived threats. Patricia voices discomfort with the idea of killing, leading to tension within the group. Damian begins to form a more selective 'security committee' focusing on identified 'problems' like the Morrison family (Jake's parents) and the Hendersons.
Meanwhile, another group of students, Madison, Emma, and Sophie, grapple with the news. Emma and Madison view the Purge as an opportunity for 'justice' against those who wronged them, creating a 'payback' list that includes Britney and Riley. Sophie is horrified and leaves the chat, while Madison and Emma begin planning to target personal rivals. They start recruiting others, including Ashley, Trevor, and Morgan, forming a group focused on hitting specific targets. Madison's group plans a meet-up to finalize target priorities and assign roles.
Tyler returns with extensive security supplies, emphasizing the seriousness of the situation. Riley reveals her mother gave her the gun safe combination and advised using the panic room, while her parents are stuck outside the state. Alex, a tech-savvy student, offers to help Riley's group with professional-grade surveillance equipment in exchange for a safe place to coordinate, intending to help vulnerable kids. Teachers also organize to protect students, led by Coach Williams and Maria. Janet, another teacher, warns about the dangers of intervening, but the others are determined to help.
Damian's 'Neighborhood Security Council' convenes, consisting of 15 members, including Derek, Linda, Carl, Steve, and Mike. Derek provides intelligence on empty houses and 'high-value targets' like Dr. Hayes and Coach Williams. Linda informs Damian that Madison's group is gathering, which Damian sees as a useful diversion. Their plan includes neutralizing organized resistance, acquiring resources, and eliminating ongoing threats. Damian assigns roles for adult resistance elimination, intelligence coordination, resource acquisition, and 'cleanup.' He identifies Dr. Hayes, Coach Williams, and Alex's father as priority targets.
Dr. Hayes warns Coach Williams about Damian's 'hit squad,' confirming that they are both on a target list for 'elimination.' Coach Williams and Dr. Hayes decide to join Riley's group, bringing weapons and medical supplies. Riley's group uses Alex's advanced surveillance to intercept Damian's communications, revealing their detailed plans and target list. They also discover Emma is planning to target Riley and that Madison is coordinating with adult attackers, including her mother Linda. Riley's group starts warning other targets.
As the Purge begins, gunfire is heard, and Damian's teams mobilize, showing a high level of organization with night vision and body armor. Emma's group successfully 'handles' Britney, Kyle, Sarah Martinez, and the theater kids, while Madison expresses her personal vendetta against Riley. Damian's group reports significant success in securing neighborhoods and eliminating resistance leaders. Mr. Davis, a teacher trying to help, is killed. Jake's home security is professionally disabled, and his family is targeted by military-grade attackers. Jake escapes through a basement window, guided by Alex's camera feeds, but his parents' house burns down. Tom Bradley is confronted by Derek for aiding the resistance and chooses to fight back, stating he chose 'humanity.' Tom and his family are killed.
Casualties mount, with Dr. Hayes confirming professional execution tactics by Damian's group, who are using the Purge for systematic elimination. Riley's group loses contact with Mr. Davis and Jake. They realize Damian planned this for months, using the Purge as a 'field test' for population management. They decide to shift from defense to offense, targeting Damian's leadership to disrupt his coordination. Maria's house is burned down, reinforcing their resolve. Tom uses demolition charges to collapse Route 7, disrupting Derek's team, while Jenna plans to infiltrate Madison's gathering to rescue captured middle schoolers. Riley's mother contacts her, revealing that trapped parents are coordinating supply drops via drones, including documentation equipment to prosecute Damian for civil rights violations after the Purge.
Damian orders Derek and Linda to eliminate everyone at 47 Pine Street, where Coach Williams is believed to be coordinating. An anonymous tip warns Riley's group of Derek's impending arrival, forcing them to evacuate to Tyler's electronic store. Damian's team at the school is ambushed, suffering heavy casualties, leading to suspicion among his ranks. Derek becomes suspicious of Damian's actions. Madison messages Riley, seeking to help kill Damian, who brutally murdered her team (Emma and others) to eliminate 'loose ends.' Damian reveals his true motive: to acquire wealth and control the town. Damian detonates the community center, killing his remaining team members (Carl, Steve, Janet, Mike) to silence witnesses, and Tom also dies. Coach Williams is also eliminated, leaving Riley's group (Riley, Tyler, Alex, Jenna, Dr. Hayes) as the last remaining resistance members. They decide to hunt Damian before he hunts them.
Damian escapes through a hidden tunnel system connecting the city, which he used to track everyone. With 8 minutes until dawn, Riley pursues him alone. As the Purge officially ends, Riley confronts Damian just as he emerges from the tunnel. Her teammates urge her not to commit murder, but Riley, fueled by anger and a desire for justice for the 43 people Damian killed, shoots him. The police arrive, and Riley accepts her fate, knowing she stopped a monster, despite the legal consequences. She tells her friends to survive, rebuild, and remember, ensuring that such an event never happens again.
