In New York City, FBI agent brothers Marcus and Kevin Copeland inadvertently ruin a drug bust. Their boss, Chief Elliott Gordon, offers them a reprieve if they safely escort sisters Brittany and Tiffany Wilson - the rich, shallow socialite daughters of the Wilson Cruiseliners CEO, whom the police suspect are the next targets in a string of high-profile kidnappings - to a weekend-long fashion event in the Hamptons. On the drive, the sisters' dog Baby nearly leaps out of the car window, causing Kevin to lose control of the car. The sisters suffer minor facial cuts and refuse to be seen with them. Kevin sends them into hiding and has his makeup expert friend Josh create prosthetic disguises so he and Marcus can replace the sisters. Kevin as Brittany and Marcus as Tiffany meet the sisters' three best friends – Lisa Anderson, Karen Googlestein, and Tori Wilson – as well as their rivals, Heather and Megan Vandergeld, and their father Warren. Gordon, along with colleagues Vincent Gomez and Jake Harper, pose as hotel staff to watch Kevin and Marcus, with both parties unaware of each other. At the hotel, a black pro basketball player Latrell Spencer, who is attracted exclusively to 'white chicks', takes a strong interest in Marcus/Tiffany, and Kevin sets his sights on New York One News reporter Denise Porter.
At the Vandergelds' annual charity auction, Latrell wins a dinner date at a restaurant with Marcus/Tiffany. Believing Denise likes rich men, Kevin pretends to be Latrell, takes Latrell's car as he takes Marcus/Tiffany on the date, to drive Denise to Latrell's house. There, he hears that the suspect, Ted Burton, has become rich after being released from prison and has no incentive to kidnap the Wilsons. With Kevin becoming romantically involved with Denise and Marcus/Tiffany unsuccessfully trying to reject Latrell, their combined antics put them under Gomez and Harper's suspicion.
At a nightclub, Heather kisses Karen's boyfriend Heath, Kevin and Marcus win a dance-off against the Vandergelds, and a drugged Latrell accidentally sleeps with Heath's friend Russ. Kevin and Marcus learn from a drunk Karen that Warren is penniless and has been taking loans from her father, and conclude that Warren is the mastermind behind the kidnappings. The next day, the real Brittany and Tiffany arrive at the hotel and discover they are being impersonated. They arrive in the Hamptons intent on exposing their "clones", as does Marcus' wife Gina, believing he is cheating on her. Realizing the Wilsons are being impersonated by men, Gomez and Harper aim to expose them, but accidentally strip down the real Brittany and Tiffany in front of Chief Gordon. A furious Gordon suspends Gomez and Harper and fires the Copelands. Having lost his job and possibly his wife, Marcus scolds Kevin for always dragging him into trouble.
Later, Kevin and Marcus discover that Warren had embezzled money through his charity. Marcus convinces Kevin to not tell Gordon and to instead redeem themselves with Gomez and Harper's help. Posing again as the Wilsons, they are chosen to perform in a final fashion show, which the real Wilsons are also performing in. During the show, the Vandergelds, furious at having been replaced on the catwalk, try to sabotage their "rivals", but end up being humiliated by Karen, Lisa, and Tori. The real Brittany and Tiffany appear and expose Kevin and Marcus, causing mass confusion. Warren begins the kidnapping, but incorrectly captures Marcus/Tiffany and Kevin/Brittany. This begins a fight between the Copelands and Heath and Russ, who are Warren's accomplices. Warren soon captures the real sisters and explains his financial troubles to his wife and daughters, unaware that his confession is being filmed by Denise. In the ensuing scuffle, Kevin is nearly shot protecting Denise, Latrell is shot protecting Marcus/Tiffany, and Kevin shoots Warren in the shoulder.
Marcus and Kevin arrest Warren while Gomez and Harper arrest Heath and Russ. Afterward, their true identities are revealed. Latrell is dismayed that Marcus is not white, seemingly not bothered that he is a man. Gordon reinstates the Copelands, Gomez, and Harper. Marcus reconciles with Gina, Kevin and Denise begin a relationship, and Latrell wins over the real Brittany and Tiffany. Tori, Lisa, and Karen admit they liked Brittany and Tiffany a lot more when Marcus and Kevin were them, and the five agree to remain friends and go shopping together.
