Woo Man Shui (Joey Yung)is a ugly girl called Peg. She doesn't have a pretty face so she gets prejudice, but she believes a good personality will compensate all that. Peg later realizes what she believes in is just an ugly girl's consolation for herself so she vows to look pretty in front of everyone, risking her life to go under plastic surgery. However, the surgery is unsuccessful where she almost loses her life but she meets a fairy. And this fairy turns her into a pretty girl so she finally gets a taste of what most pretty girls' receive such as many "special treatment". Pretty Peg now receives more opportunity at work, and even uses cunning approaches to retailiate against her enemy "Mr. Jerk" Leonardo(Roger Kwok), pushing him to his lowest point in life. She has fun realizing her revenge though her point of revenge is to have Leonardo repent for his wrongdoings. In the end, Peg realizes that a pretty person without a good personality is pointless. Is that her realization or just a pretty girl's snobby remark?
