Sarah Gale enjoyed a happy childhood with two loving adoptive parents, but she'd been desperate to track down her birth mother and been trying to do so for 20 years. The programme found Susan who, after having Sarah, had moved to South Africa in the 1970s and went on to have a son. Three years after being reunited, Davina and Nicky hear how mother and daughter have grown close, and Susan prepares to meet Sarah's adoptive mother Rosemary for the first time. Plus an update on Jeannie Elgar, who met her brother's adoptive sibling Robert, and Stella, who was reunited with daughter Maxine after she made the decision to have her adopted at 18 months old.
