White Chicks (2004)
They're going deep undercover.
Two FBI agent brothers, Marcus and Kevin Copeland, accidentally foil a drug bust. To avoid being fired they accept a mission escorting a pair of socialites to the Hamptons--but when the girls are disfigured in a car accident, they refuse to go. Left without options, Marcus and Kevin decide to pose as the sisters, transforming themselves from black men into rich white women.
