February 2025. Excavators dig three meters into the former Castalloy factory site in North Plympton, Adelaide. They're searching for three children who vanished sixty years ago, based on testimony from the factory owner's son who claims he saw them enter his father's property and never leave, and two brothers who say they were paid to dig a grave-sized hole here days after the disappearance.

Professor Maciej Henneberg works with archaeological precision. The soil reveals disturbed earth, a pit matching the exact dimensions describes. Evidence that something was buried here. After decades of searching, perhaps the Beaumont children will finally be found.

But the excavation ends with no remains. Only questions.

This is Part Two of our investigation into Australia's most haunting missing persons case. We examine three major suspects including millionaire Harry Phipps, who lived 300 meters from where the children were last seen. We explore why three excavations using cutting-edge technology found grave-like anomalies but no bodies. And we uncover a disturbing pattern: seven years after the Beaumont children vanished, two more girls disappeared from Adelaide Oval under strikingly similar circumstances.

Sixty years of searching. Over one hundred suspects. Three children still waiting to be found. And uncomfortable questions about who was protected and why.

Content warning: This episode discusses the disappearance and presumed murder of young children, and examines systemic failures in their protection.
