Follow Roger Fisk, a descendant of a soldier on the Union side who went to war, not just to preserve the Union but also to free the slaves. Using the letters written by his ancestor as a guide, we'll go on an epic journey to reveal his motive for traveling hundreds of miles through battlefields to go to war. We also meet Christian Latham, a 22-year-old descendant of a private, who wants to experience what his ancestors did 150 years ago in their struggle for freedom.
