Davina McCall and Nicky Campbell return to help more people reunite with long-lost relatives, beginning with 67-year-old Christine Rose's search for the sisters she was separated from at the age of four when her mother was prosecuted for neglect. The three young girls were taken by social services during the night and sent to separate children's homes. Nicky leads the search for Christine's sisters and the team makes remarkable discoveries, revealing layers of family that she never knew existed.
