Quiet teenager Marc Hall (Israel Broussard) arrives as a new student at Indian Hills High School in Agoura Hills, California. He is befriended by fame-obsessed Rebecca Ahn (Katie Chang). While at a party at Rebecca's house, the pair check unlocked vehicles on the street, taking valuables such as cash and credit cards.
When Marc mentions that one of his wealthy acquaintances is out of town, Rebecca persuades him to join her in breaking into to his house. Rebecca steals a handbag, mentioning that her idol, Lindsay Lohan, has the same one. She also steals cash and the keys to a Porsche, which the pair use to flee the scene. With the cash, the two go on a shopping spree, affording themselves the luxury lifestyle they admire in magazines.
Marc visits a nightclub with Rebecca and her friends Nicki (Emma Watson), Nicki's adopted sister Sam (Taissa Farmiga), and Chloe (Claire Julien), where they rub shoulders with celebrities such as Kirsten Dunst and Paris Hilton. While researching Hilton on the Internet, Marc and Rebecca realize that she will be out of town. The pair go to her house, and finding the key under the doormat, they go through Hilton's belongings, taking some jewelry. Rebecca then flaunts a stolen bracelet to Nicki, Sam, and Chloe at a party.
At Nicki's request, Rebecca and Marc take her, Sam and Chloe back to Hilton's house. The group marvels at the excess of Hilton's lifestyle, and steals shoes, bags, dresses, cash, and jewelry. Marc and Rebecca return to rob Hilton's house on a third occasion. The pair also decides to rob the home of Audrina Patridge, once again using the Internet to determine when she will not be home. The entire group uses the same method to burgle the home of Megan Fox, with Nicki's younger sister Emily (Georgia Rock) squeezing through a pet door to gain access to the home.
The group enters the home of Orlando Bloom and his girlfriend, Miranda Kerr. The girls proceed to steal similar items, while Marc finds a case filled with seven of Bloom's Rolex watches along with a roll of cash. Chloe then helps Marc sell the watches to her friend, a night club manager named Ricky (Gavin Rossdale). The group returns once again to Hilton's house, with Sam's boyfriend Rob, who also steals from the home.
A news report releases captured CCTV footage from the robbery at Patridge's home. This concerns Marc, but Rebecca is undeterred and instigates a burglary at the home of Rachel Bilson. Word spreads amongst the group's social circles, and the girls boast of their accomplishments at parties, also posting photographs of the stolen items on social media sites. The group ultimately breaks into Lohan's house and robs it. Shortly after, Rebecca moves to Las Vegas with her father due to troubles at home, leaving some of her stolen items with Marc, who inadvertently helps Rebecca transfer stolen items across state lines.
News reports of the Hollywood Hills burglaries intensify, with the media labeling the group "The Bling Ring". CCTV from several robberies in addition to the evidence on social media allows authorities to identify the group. Police arrest Marc, Nicki, Chloe, Rebecca, Rob, and Ricky, but Sam is not identified in the footage and avoids arrest. Marc cooperates with the police, informing them on the details of the burglaries, much to the chagrin of Rebecca, who has been identified as the ringleader. A Vanity Fair journalist interviews Marc, who is remorseful, and Nicki, who vehemently suggests the others were at fault, and that she was simply involved with the wrong people. Rebecca also denies being at fault and tries to pass the blame for all of this and Marc and her other friends. The group is ultimately prosecuted, receiving varying amounts of jail time and is ordered to collectively pay millions of dollars in restitution for the stolen items.
The group serves its jail time, and Marc and Rebecca each go into seclusion from the press. They never see or speak to each other again, and both of them steadfastly blame each other for the robberies.
In the final scene, set a few months later, Nicki is on a talk show talking about her time in jail, and reveals that her cell was next to Lohan's. After digressing, she turns to the audience (and the viewers) as she finds a way to enhance her newfound notoriety, telling them to visit her now-popular website detailing her life after "The Bling Ring".
