Baby Cunningham grew up tormented and picked on by her brother, Spencer, and his best friend, Mitchell Sterling. She went through years and years of torture. That is, until her Mom sent her away to Australia on a trip, for four years, only to make her family seem more glamorous. When Baby gets back, she's fully aware of how much she's matured. So maybe, just maybe, it's time to get a little revenge on Mitchell? How far will she go, and how long can she keep up with it before she might start to have a teensy little crush?
