The Hamilton triplets - Madison, Park, and Lexington - are accustomed to living in the public eye. Heiresses to a billion-dollar media empire, they have been raised in New York's most elite social circles and, at 16, know firsthand the demands of being celebutantes. There are people to impress, appearances to make, and paparazzi to outrun. Not to mention high school to finish.

The school year's almost over, and Madison, Park, and Lexington Hamilton are about to head to Capri. Before vacation comes work, however, and with the opening of Hamilton Holdings' latest venture, Cleopatra, the newest and most expensive club in Manhattan, the girls must throw one incredible opening night party.

Before the night ends, the body of classmate Damien Kittle is found in the club with a bloody wound on the side of his head and the high-heeled murder weapon lying nearby. The shoe belongs to another student: Concetta Conoli-an unfortunately unfashionable diet food heiress.

The paparazzi are having a field day, and they're determined to drag Cleopatra through the mud with Concetta. Madison, Park, and Lexington can't allow their club, and a fellow heiress, to be slandered in this fashion. The girls know the real murderer is still out there, and they're willing to bet their sizable inheritance that the police won't be able to unravel the mystery without their help.
