Mia and Michelle couldn't look more alike - or act more differently. Mia's always been the glamorous one, the one everyone wants to get close to. And now she's a model, on the edge of fame. But Mia can't resist the illegal thrills that come with fame. When disaster strikes, her mousy look-alike sister has to pretend to be Mia. Michelle saves her career, and turns out to have star quality too. She's even got someone to fall in love with her - a man Mia wants almost as much as she wants to be a supermodel. That's something Mia will never, ever forgive . . .
