Scars introduce White Cloud, a young Plains Cree boy, in the year 1870, when the last great smallpox epidemic swept through the prairies. After witnessing, one by one, the death of his entire family from the illness, he summons the strength to journey on to find a new home and deliver himself from the terrible disease. But will he make it?

Scars follows White Cloud and the people he encounters, as he struggles to survive against impossible odds. By learning about the bravery and perseverance of his ancestor White Cloud, Edwin summons his own courage and travels to confront the main source of his despair: the father he barely knows.
