On a summer's day in 1992 a thirteen year old schoolgirl called Prue Bird vanished without a trace.

Her mother Jenny returned from the local swimming pool and found only an open door and an uneaten meal.

It became one of Victoria's most enduring mysteries.

For Jenny Bird there was an extra twist to the torment. Was the disappearance connected to the underworld links of Prue's doting grandmother - and to the Russell Street police station bombing six years earlier?

For the first time all the stakeholders in an astonishing crime saga tell their side of a real life 'underbelly' saga still impacting today on three generations of one family.
