As war overtakes the frontier, Emma's family farmstead is attacked by Dakota-Sioux warriors; on that same prairie, Oenikika desperately tries to hold on to her calling as a healer and follow the orders of her father, Chief Little Crow. When the war is over and revenge-fueled war trials begin, each young woman is faced with an impossible choice. In a swiftly changing world, both Emma and Oenikika must look deep within and fight for the truth of their convictions - even as horror and injustice unfolds all around them. Inspired by the true story of the thirty-eight Dakota-Sioux men hanged in Minnesota in 1862 - the largest mass execution in US history - Dovetails in Tall Grass is a powerful tale of two young women connected by the fate of one man.
