We revisit three more families who were separated by extraordinary circumstances. Divorced couple Marion and James united in their search to find the son they gave up for adoption as teenagers. Their reunion brought about a dramatic twist that had huge consequences for all of them. Ray went in search of his brother Arthur in 2016, but was shocked to find he had 11 other siblings as well. We also catch up with Laura, who reunited with her Nigerian father Andy and brother Nten.
