Sound designer Callie Roberts is a single mother. And she's come to rely heavily on her best friend and neighbour, Suzy. Over the past few lonely years, Suzy has been good to Callie and her rather frail daughter, Rae, and she's welcomed them into her large, apparently happy family. But Callie knows Suzy's life is not quite as perfect as it seems. It's time she pulled away and she needs to get back to work. So why does she keep putting off telling Suzy? And who will care for Rae? In the anonymous city street, the houses each hide a very different family, each with their own secrets. Callie's increased sense of alienation leads her to try and befriend a new resident, Debs. But she's odd - and you certainly wouldn't trust her with your child - especially if you knew her past.
