The Milk River Cree tribe has an age-old prophecy: When the white buffalo herd returns to America, world peace will follow. After years of raising buffalo, the Milk River Reservation has finally bred a single white calf. And the calf has gone missing. Ne'er-do-well Tommy Little Moon is on a mission: Find the errant white buffalo before hunters do. When Tommy's pickup truck breaks down outside the New Order Amish community, Tommy has no choice but to accept aid from brash blockhead Micah Miller. Tommy and Micah have three months to find the white buffalo before she breaches the international border. If they can manage not to kill each other, that is.
