S01E01 — Episode 1

2008 – a glorious May bank holiday weekend. A four year old boy goes missing after a neighbourhood barbecue. Believed to have been abducted, a nationwide search and media frenzy ensue, but the boy is never found. Present day – the wettest spring on record. Workmen digging up a burst water main uncover a body under the communal garden. Little Callum Reid – buried just yards from his own front door. The missing boy never left Arcadian Gardens. In 2008, Arcadian Gardens is a desirable address - a suburban oasis with comfortable detached homes overlooking a private shared garden. Unlike most anonymous urban streets, the residents pride themselves on their sense of community. Children play in the communal garden. People feed each other's pets and water one another's plants and, of course, every May Bank Holiday there's the annual neighbourhood barbecue. Then little Callum Reid from No. 4 goes missing and nothing is ever the same again. Five years on, Arcadian Gardens is a very different place. An address synonymous with tragedy. The grief-stricken parents’ and their neighbours’ lives were torn apart by the events of that long May weekend and even after all this time the wounds are still raw. Then, on the eve of the fifth anniversary of his disappearance, Callum’s body is discovered, buried only yards from his own front door. And the nightmare begins all over again.
