It's 1746 and Georgian London is not a safe place for a young Black man. Charles Ignatius Sancho must dodge slave catchers and worse, and his main ally - a kindly duke who taught him to write - is dying. Sancho is desperate and alone. So how does the same Charles Ignatius Sancho meet the king, write and play highly acclaimed music, become the first Black person to vote in Britain, and lead the fight to end slavery? Through every moment, Sancho forges ahead to see how much he can achieve: "I had little right to live, born on a slave ship where my parents both died. But I survived, and indeed, you might say I did more."
