A stream runs out of the mountains and races through a small town by the Montana border. On its banks two teenage boys - one white, one Native American - watch and talk and take in the stories about the stream's source, a mysterious canyon high in the Rockies where glaciers feed the turquoise waters.

Meanwhile the boys have stories of their own - about how the earth came to be, and the mountains, and the tribes, and the bears and the warriors. And they have other stories too - about a crippled brother, and the hard deaths of a father and a mother, the bullets and blood of the 1973 Wounded Knee Uprising, about a girl more beautiful than moonlight.

Sometimes it's difficult to separate the myth from the real.

A trek to find the source of the mountain stream could set everything right. It could bring the healing, and understanding, and the connection to all things natural, supernatural, and spiritual the boys crave. If only they can finish the journey. If only the truth can find them when they do.
