Sonia yearns for sharp objects and blood. But now that she's rehabilitating herself as a "normal" mother and mathematics teacher, it's time to stop dreaming about slicing people's throats. While being the wife of Melbourne's leading drug lord and simultaneously dating his best mate is not ideal, she's determined to make it work. It does work.

But is protecting the kids really Sonia's motive?
