Much to Cooch's anger, Ray comes to suspect a conspiracy and cover-up involving the reservation and Leo's murder. After being told to find 'the source', Ray and Crow Horse come across a government-sponsored plan to strip mine uranium on the reservation. The mining is polluting the water supply and fueling the bloody conflict between the reservation's anti-government ruling council and Milton's pro-government natives. While the land is not owned by Milton, he receives kickbacks from the leases; Ray and Crow Horse discover Maggie's body at the site.
