After a Sioux uprising in 1862, two thousand Winnebago Indians were forced from their Minnesota homes to a reservation in Crow Creek, South Dakota. Many Indians died from the inhumane conditions encountered on the journey and even more at their destination; Crow Creek had little food, no farming, and no weapons for hunting. Kunu, a ten year old boy, and his grandfather vow to return to their homeland in Minnesota. Knowing they will be shot on sight if caught trying to leave, Kunu and his grandfather secretly make plans to escape in a dugout boat. They eventually trip over hundreds of miles of river, through many adventures and dangers.
