Davina McCall and Nicky Campbell investigate two firsts for the show.
Andy McNichol from Walsall is the first father to ask the team to help find his child, who was adopted at birth against his wishes.
When Andy’s girlfriend, Brenda, became pregnant, he hoped to raise their son together but, unable to marry Brenda, she broke off contact and gave their son up for adoption.
Also featured is the story of Mary Davies from London, who is the first deaf person to appear on the show.
She is searching for her birth mother, who was young and unmarried when she had Mary 56 years ago.
Mary spent her first six years in children’s homes as she waited to find a family who were willing to adopt a deaf child.
