On a whim, American teenager Daphne (Amanda Bynes) boards a plane to England to find the father she never met. Upon arriving there, though, she makes a startling discovery: The man she's looking for is Lord Henry Dashwood (Colin Firth), a member of the British upper class, who is running for political office. Lord Henry didn't know Daphne existed, but he welcomes her into his life. However, she isn't so sure -- and his family and his current betrothed look on her disapprovingly.
