The movie follows FBI agents Kevin and Marcus Copeland (played by Shawn Wayans and Marlon Wayans), two bumbling undercover agents who are assigned to protect the heiresses Brittany and Tiffany Wilson (played by Brittany Daniel and Maitland Ward) from a kidnapping plot. However, during a botched operation, Kevin and Marcus accidentally ruin their chance to catch the kidnappers and are suspended from duty.
Determined to redeem themselves, Kevin and Marcus come up with a risky plan to go undercover as the Wilson sisters themselves. With the help of prosthetic makeup and disguises, the two agents transform themselves into Caucasian versions of Brittany and Tiffany and infiltrate their social circle at a Hamptons resort.
As Kevin and Marcus struggle to maintain their disguises and fit in with the wealthy and glamorous lifestyle of the Wilson sisters, they encounter a series of comedic mishaps and misunderstandings. Along the way, they form unlikely friendships and romantic connections, including with fellow resort guests and their fellow FBI agent Lisa (played by Busy Philipps).
In the climax of the film, Kevin and Marcus finally uncover the identity of the kidnappers and thwart their plot to abduct the Wilson sisters. They also reconcile with the real Brittany and Tiffany, who are initially shocked by the deception but ultimately forgive Kevin and Marcus for their well-intentioned actions.
The film ends with Kevin and Marcus returning to their duties as FBI agents, having successfully completed their mission and earned the respect of their colleagues. They also reaffirm their bond as brothers and partners in crime-fighting, ready to take on whatever challenges come their way.
