1884. 15-year-old George Gillies lives in the Washington Territory, near the border with British Columbia. In this newly settled land, white immigrants have an uneasy relationship with the Native Indians. When George and his siblings discover the murdered body of a local white man, suspicion immediately falls on a young Indian named Louie Sam. George and his best friend, Pete, follow a lynch mob north into Canada, where the terrified boy is seized and hung. But even before the deed is done, George begins to have doubts. As George uncovers the truth--implicating Pete's father and other prominent locals--tensions in the town rise, and he must face his own part in the tragedy.
