Heir Hunters race to find family on one of their most valuable ever cases. When an NHS pathologist passes away, the search leads to a family torn apart by tuberculosis. As the hunt for heirs hits a dead end, records eventually lead halfway around the world and reveal that the family's youngest members were forced to embark on an adventure of a lifetime.
In a second hunt, medical matters are also at the forefront with a grandfather who served in the Royal Army Medical Corps, helping the wounded on the frontline of battle. As the search unfolds the team learns that his son, an ambulance driver, played his part during another great war, this time on the home front during the Blitz. With heirs receiving potentially life-changing sums of cash, they learn about the bravery of their unsung wartime heroes.
