Sixteen-year-old Poppy (Emma Roberts, Nancy Drew) is a self-obsessed, incorrigible brat who lives a pampered life in her L.A. world. Though she's handed credit cards with unlimited balances and surrounded by countless hangers on, Poppy can't escape the mounting frustration she feels with her family situation. And she makes sure that everyone knows it.

After an over-the-top prank pushes her father (Aidan Quinn) one step too far, Poppy is shipped off to an English boarding school. Finding herself in a foreign world of early curfews, stern matrons and mandatory lacrosse, the American princess has finally met her match: a school of British girls who won't tolerate her spoiled ways.

Under the watchful eye of the school's headmistress (Natasha Richardson) and surrounded by a new circle of friends, Poppy begrudgingly realizes her bad-girl behavior will only get her so far. But just because she must grow into a fine young lady doesn't mean this Wild Child won't be spending every waking hour shaking up a very proper system...
