But, as soon as they realise she's a Harvard- educated lawyer, they flee. Harper's best friend is a magazine editor who suggests Harper go on assignment for a month as a "dumb blonde" and see if it changes her dating perspective. So for two weeks, Harper goes undercover. She changes her wardrobe, her conversation, her body language. The result is a series of comical encounters. Soon, Harper must take a good look in the mirror and realise that it's not just men who judge people on their looks.
