Wanting to get mothers, fathers, sisters, brothers, sons and daughters back together after sometimes a whole lifetime apart, the pair are about to take us, as well as the people they're helping, on a very emotional journey.
In tonight's opening episode, Alan Ross-Harper is searching for his birth mother who gave him up for adoption in 1958. After a long and difficult search, Alan's mother was tracked down to New Zealand – and in a rare twist, is married to his birth father. We'll get the tissues out for the moment they're reunited!
We'll also meet 68-year old Susan Udy who is searching for the daughter she gave up for adoption 46 years ago. Susan wants to give her a ring that belonged to Susan's mother, and we'll be there when she finally gets to do that.
