Who's That Girl?

Charlotte and Lottie have absolutely nothing in common - except they`re the same person. Thirty-something Charlotte has a high-flying PR agency, a serious boyfriend and all the trappings of success - she`s living the dream, so why is it so stressful? Twenty-one-year-old Lottie has just moved to London with dreams of becoming a writer. Carefree and single, she`s having fun - and on the brink of making some big mistakes. So when a cosmic glitch brings Charlotte face to face with her younger self, she hatches a plan to teach her all the things she knows now: wear sunscreen, stay away from PVC trousers and Do Not Sleep With That Guy. But what she doesn`t expect is Lottie has a few lessons of her own. And rewriting your past can seriously mess with your future . . .
