This two-part documentary follows four women adopted in South Asia as they try to find their birth families, beginning with two women in Sri Lanka. Rebecca is back for her third search, investigating the government ministries, shanty towns and hospitals that might offer some clue to her mother's whereabouts. Ria from Scotland is returning for the first time, clutching a photo and a paragraph saying her birth mother wanted no contact after the adoption. Will either of them find the answers they are looking for?
