The four-part series focuses on the lives of sisters Theresa (Anna Maxwell Martin) and her older head teacher sibling, Helen (Rachael Stirling).
The siblings are close, and the series begins with them spending a sunny evening together in Theresa and her partner Fraser (Rhashan Stone)'s garden, where they are having a barbecue with their families.
But the calm doesn't last long, as when Theresa's 10-year-old son Ben (Fraser Holmes) asks to play in a nearby park with his cousin Eva (Amelia Bea Smith), things soon take a dark turn.
Theresa makes no secret about the fact she is anxious for the children to head out alone, but Fraser is relaxed and tells her it will be fine.
She's right to be nervous, though, as the kids don't return on time - and when Theresa goes out in search of them she's left even more suspicious after she comes across them fighting at the edge of a woodland area.
Later that evening, the children are acting strangely subdued. Then the family's devastated neighbour, Jean (Jodie McNee), calls in, revealing that her 10-year-old son Alex (Jonas Armstrong) has gone missing.
Try as she might, Theresa just can't help but wonder if her son knows any more about the little boy's disappearance than he's letting on.
The neighbourhood all gather to help with the search for Alex, but what if he's been murdered? And what if the kids know more than they're saying.
The series has been written by Sophie Petzal - who previously worked on Channel 5's Blood starring Line of Duty favourite Adrian Dunbar.
