SYNOPSIS

Adelaide was founded as a utopian ideal — then five children vanished in broad daylight: the Beaumont children in 1966, and Joanne Ratcliffe and Kirste Gordon in 1973. No bodies. No evidence. No one charged.

These events fractured the city’s psyche and seemed to usher in a wave of brutal crimes that followed, helping recast the “City of Churches” as the “Serial Killer Capital of the World.”

Decades later, two citizen-led investigations reopen the emblematic cases, driven by a desperate belief that if the origin mystery can finally be understood, the city might begin to understand itself. But what starts as a hopeful hunt spirals into rumour, psychics, and spectacle — revealing how a mystery that never ends exposes far more about the living than the dead.
