I stare at the photo of my beautiful daughter. Her hair is shining and her face is lit up with a smile. The man with her looks so happy too. But my mother’s instinct is screaming. I know something is terribly, terribly wrong. And I know what I have to do… I wish I could hold her tight. See if she still wears the same perfume she always wore. But my daughter blames me for her father’s death. She won’t even talk to me… I just know she isn’t really safe with her boyfriend, Garth. I will keep my distance and I will just watch her. For now.

Her chest tightens, her heart speeding up. The kitchen is chaos. She steps on something hard, and looks down. Toy dinosaurs are scattered everywhere. But her son is nowhere–her baby boy is gone.

She knows everything about you… but can you trust her? I walk in to my interview with Ava Green and carefully hand over my application. It’s all made up, of course, but Ava doesn’t have to know that. There is so much worry in her blue eyes. Her phone pings with constant messages and a small stain marks her crisp shirt. Breakfast with her two little girls before heading out to this high-flying job every morning can’t be easy. Ava needs me, I think. More than anything.

Caroline twitches aside her curtains to see the new family moving in. A mother – beautifully dressed in expensive clothes – and two young children. Where is her husband, she wonders? And why are they moving in to the smallest house on the street? They really don’t seem the type. But Caroline believes it’s important to be welcoming. It’s important to know everything that’s happening on West Street.

How well do you really know your own family? The wife: Eve is desperate for her life to be perfect. Living in a beautiful house, with gorgeous views of the countryside, is all she’s ever wanted. And she’ll do whatever it takes to hold onto her dream life. The son: Joe is a model student; he never puts a foot wrong. He knows his mother wouldn’t tolerate it. Until the night of his sixteenth birthday party, when things go horribly wrong and someone in the house is left fighting for their life. As the blue flashing lights of the police and ambulance arrive, all eyes are on the Griffiths family.

It’s the phone call every mother dreads. I’m climbing into the car after a trip to the grocery store. As the engine starts, my phone rings. It’s my stepdaughter, Shelby, who is babysitting my three-year-old Millie. "I only went upstairs for a second," she says through her sobs. "She’s gone." When the police turn up, Shelby’s story starts to unravel. What is she hiding? Then I get a message saying, "Your husband is not who you think he is." Suddenly, my family feel like strangers. Everyone has a secret - even me.

I never thought I would end up here. Alone, in a cold one-bedroom apartment, only seeing my precious daughter once a week. Another woman is living the life that was once mine. I wish I was still married to my ex-husband, the love of my life. I dream of tucking my five-year-old child into her ballerina bed sheets every night. I miss living in a beautiful house, the perfect family home, with a winding staircase and a sprawling garden. I’d do anything to be with my family again. To start over and prove to them that I’ve changed, that I won’t lose control like before.

In the middle of the night, Claire wakes up to discover that her beloved daughter, Julia, is dead - and life, as she knows it, is over. Searching for answers, Claire stumbles upon a pile of letters, hidden under Julia’s bed in an old, battered shoebox, and feels closer to her daughter than ever before. They tell her that Julia was happy, that she was thriving at university, that she was in love. But as the letters go on, Claire starts to feel uneasy at something hidden between the lines. Even as she grieves, she must prepare to face a shocking discovery.

Wife: I couldn’t be prouder of my charming husband and quiet and kind son. I’ve poured everything into my little family, so I choose to ignore my husband’s late-night phone calls and wandering eye. I won’t let anything ruin my perfect life…

I gaze at my husband’s once handsome face, so still and pale in the hospital bed. The doctors say I should keep talking. He might be able to hear me even after the terrible accident that left him fighting for his life. But all I have to whisper to my husband is this: "I know what you did."

Elizabeth is Joe’s foster mother, but she loves him like her own. The five-year-old, who adores superheroes and watching the birds outside, is the child she has dreamed of. As she looks into the garden, where he was playing just moments ago, her heart feels like it has been ripped from her chest. She was meant to save Joe from his birth mother who almost harmed his chances at life. The woman who has been trying to desperately get him back. She was meant to protect Joe from her husband. The man who, right now, lies to the police, saying he was making breakfast when Joe disappeared.

ME: Staring down at the sweet baby in my arms, I feel panic instead of love. Because this isn’t the child I gave birth to. My husband whispers to the midwife. They all think I’m going crazy. But the tiny boy in my arms is crying again. I’m certain: he knows I’m not his mummy. And I’ll do whatever it takes to get my son back.

I am cooking spaghetti, his favourite, while he plays in the garden. But when I look up, he’s gone. I call the police, my hands shaking so much that I hit the wrong digits twice. "My son is missing." When the police turn up, I’m trapped in the web of my lies. I have hidden the truth from eight-year-old Riley, my little boy who loves climbing trees and always has scraped knees. I have hidden my secret from everyone.

You tell him everything. The husband you adore, the father of your child, your best friend. He knows, just by looking at your sage green eyes, when something is wrong. The two of you can communicate with a glance or a touch of the hand. Except what if you can’t? What if your happy marriage has plastered over one huge lie? A lie you have even started to believe yourself in order to survive?

I’ve been married to my kind, loving husband Lachlan for over twenty years. He’s my everything. We have two teenage children, a beautiful home and I feel so lucky to live this perfect life. Until my best friend says something that makes me doubt everything… She whispers it’s strange Lachlan has lived nearby to two unsolved murder cases. First, the murder of the woman in the small, Scottish village where he grew up and more recently the shocking death of a woman who lived round the corner from us. The thought makes my head spin. It’s just a coincidence, surely?

All Malia needed was a single litre of milk, and now she's surrounded by police and Zach has disappeared. Detective Ali Greenberg knows that this is not the best case for her - not with her history, but she has to get back to work at some point. Edna is worried about the new residents at the boardinghouse. She knows Mary would turn in her grave if she knew the kinds of people her son was letting in. And then there is someone else. Someone whose heart is broken.

Every family has secrets, and on the hottest day of the year, the truth is about to come out. As a tragedy unfolds behind closed doors, the dawn chorus is split by the wail of sirens. And one by one the families who tried so hard to welcome the Wests begin to realise: Hogarth Street will never be the same again.

Megan waits at the school gates for her six-year-old son, Daniel. As the playground empties, panic bubbles inside her. Daniel is nowhere to be found. According to his teacher, Daniel’s father picked up his son. Except he and Megan are no longer together. After years of being controlled by her cruel husband, Megan finally found the courage to divorce him. Hands trembling, she dials his number, but the line is dead. Six years later, Megan gets the call she has dreamt about for years. Daniel has walked into a police station in a remote town just a few miles away....

Once, so very long ago, she watched him like this when he came to pick her up from a date. Her stomach fluttered and burned with infatuation and desire. She would watch him walk up the path and think, 'This must be love.' But that was so very long ago. Now Liz is wary and afraid. She has made a terrible mistake, and it cannot be undone.

Thirteen years ago, Cole and Lisa Shipley were fostering an infant with hopes of adopting her. Overnight everything was turned upside down, when the child’s mother bled to death on their front doorstep. Her last words: He’s coming here…for her! Save her. Afraid, bewildered, and with a baby in their arms, they fled. The longer they hid, the guiltier they looked. Now in a small Colorado town under assumed identities, they’ve been seemingly safe.
