Davina McCall and Nicky Campbell follow three stories of sons coming to terms with the past, including Marc Wolfe's struggle to form a bond with his birth mother Esther, who lives in New Zealand. However, his search for identity didn't end there as researchers were able to reunite him with his birth father David, and the pair have grown close. One significant hurdle remained in the form of introducing David to his adoptive father Terry, and cameras were there as Marc introduces his two dads to each other.

In our second episode we follow reunited siblings, Geoffrey Tonks and Barbara Jacobs as they investigate a family mystery and try to trace a missing sister.

Davina McCall and Nicky Campbell revisit more of the programme's most memorable searches, catching up with two people whose lives have been transformed. Kathleen Fraser Jackson was reunited with her birth mother in Canada, and the programme follows her to Jamaica to meet her youngest sister Peta Gay for the first time. The second story has never been shown before and features twins who were separated as babies.

Episode 2 follows three families who have faced challenges building their new relationships. Our first story catches up with Brenda Rhensius who approached us 8 years ago hoping to find her daughter Joanne. Amazingly, both mother and daughter now lived in South Africa and we were able to reunite them in Cape Town. In our second story, we catch up with former England rugby player Spencer Brown and his sister Margot who were reunited last year. Separated as infants, Spencer and Margot had very different experiences growing up; he had a happy, loving adoption, while she spent time in care. Our third reunion was not originally shown on Long Lost Family because the situation was too sensitive for the cameras. It’s only now, three years after the family first met, that they feel ready to share their extraordinary experience.

The first episode catches up with Julie Roberts who reunited with her birth mother Marion last year leading to an incredible revelation. “Finding mum was amazing but for her it’s been the start of a new search.” explains Julie. The second story follows Christina Barlow as she travels 5000 miles to Colombia to spend time with the birth parents, who gave her up in extreme circumstances. On this trip Christina spends time with her full siblings, who never knew she existed.

A catch-up with Roy David - who went looking for his daughter Cheryl in 2021 - and Maria Costantino, who discovered in 2018 that her birth mother had passed away.

Episode two catches up with people whose lives have been changed in the most unexpected ways. Just last year Vanda James was stunned when Davina revealed that her long lost brother Kenneth had not only been found, but had undergone gender transition and was now in fact her sister, and called Debbie. We revisit the siblings as they celebrate Debbie's birthday and discover how the reunion has changed the sisters' lives in ways they could never have imagined. In the second of tonight's stories, when Chris and Sue Ellerton came to us searching for the son they had put up for adoption as teenagers, it was a first for Long Lost Family. Never before had we taken on a joint search on behalf of a couple looking together for their child.

We catch up with people whose lives have been changed forever, to find out 'What Happened Next?', including a mother and daughter, and two siblings.
