Well-known Australians play detective as they go in search of their family history, revealing secrets from the past.

Taking us to all corners of Australia and the globe are stories of individuals seeking to find the definitive answer to where they came from. Along the way secrets are uncovered and histories revealed — from resistance fighting to murder, from child abandonment to adoption, and from nineteenth century abortion to twentieth century shell shock — with each individual discovering that their ancestors form an integral part of not only their own identity, but that of the nation. 

This is a fascinating chronicle of the social, ethnic and cultural evolution of Australia’s national identity.
