White Chicks (2004)

Despite their best efforts, agents Marcus and Kevin Copeland have worked their way down to the bottom of the FBI food chain. Their most recent bust was a failure and they are hanging onto their jobs by a thread. When a plot to kidnap spoiled socialite sisters Brittany and Tiffany Wilson is uncovered, the big case is given to Marcus and Kevin's rivals Vincent Gomez and Jake Harper. To add to their humiliation, Marcus and Kevin are handed a thankless menial task--to escort the Gucci-clad spoiled brats safely from the airport to their hotel in the Hamptons. Even they can't get that one wrong. Right? When Tiffany's pampered pooch, Baby causes a traffic mishap, a fight ensues and the two women are disfigured--well, if you call a fat lip and a cut nose disfigurement, which to these looks-obsessed socialites it certainly is. The heiresses refuse to show their less than perfect faces at the important society weekend fearing they could lose the highly coveted cover of Hamptons Magazine to their archrivals Heather and Megan Vangergeld. Faced with the prospect of unemployment, Kevin hatches a plan: He and Marcus will go undercover as the demanding divas and, in the process, try to snare the kidnappers and restore their reputations. With the real Wilson girls safely ensconced in a luxury New York hotel, Marcus and Kevin assume their identities and spring their most unlikely sister act on the unsuspecting creme de la creme of Hamptons society.
