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.
