Davina McCall and Nicky Campbell return for this new series about foundlings: people abandoned as babies in the first hours or days of their lives, who until recently have had no way of discovering the most fundamental facts of their identity. 

From the extraordinary true story of two babies left on either side of the Irish border during the 'Troubles' to a baby boy left in a corned beef box in Greenhithe in 1963, we use ground-breaking DNA technology and painstaking detective work to try piece together their pasts and give them the answers they're searching for.
