Singer-songwriter and talent show judge Pixie Lott hopes to confirm a family story that she has Italian ancestry from Verona, but instead discovers ancestors battling poverty and hardship in London. On her dad's side, Pixie learns of her great-grandfather's harrowing and surprising experience in the First World War. And, wondering if she has any musical genes, Pixie is delighted to discover three generations of military musicians, whose legacy gives her an opportunity to sing with the band of the Household Cavalry.

Ed Balls, former Labour politician, sequinned Strictly dancer and TV presenter, grew up in a family that wanted to make the world a better place. His mother Carolyn's dementia means she can't share their family history with him, so he sets out to discover what kind of characters his ancestors were. Rumours on his paternal side about a link to Nelson's ship HMS Victory lead Ed to Portsmouth and the story of his great-great-great-grandfather William Dunbar, an assistant surgeon. But as he unravels Dunbar's medical career, he unearths a dark history of abuse and horror at a Kent workhouse. On his mother Carolyn's side, he feels a deep connection with Christopher Green, an agricultural labourer put on trial at Norwich Castle after he stood up to defend his livelihood and community.
