The story begins when Lila Blanket's prophetic vision compels her to send her daughter Grace into town, setting in motion a chain of events that ends in Grace's murder at the hands of oilman John Hale. Grace's death is only the first in a series of killings that terrorize the community, and federal investigator Stace Red Hawk arrives to slowly build a case against Hale while corruption obstructs justice at every turn. Nola Blanket, who witnessed her mother's murder and inherited her wealth, navigates marriage to a white man while fearing she will become the next victim of the cycle of exploitation. Although Hale is eventually convicted, the violence does not end, and the Graycloud family is finally forced to flee their burning home.

The strange death and apparent resurrection of John Stink, alongside the shooting of John Thomas, illustrate both the violence and the spiritual resilience that coexist in the community. Belle's fierce confrontations with eagle and bat hunters show that even sacred animals are under assault from white encroachment, and her arrests reveal how the legal system is weaponized against the Osage.

The exposure of Ruth's husband as one of Hale's conspirators in the novel's final pages confirms that the threat to Osage women extended into the heart of their own families.

The conspiracy behind the Osage murders is revealed gradually through a series of escalating discoveries, quiet confrontations, and devastating realizations. From the earliest scenes — the arrival of Nola's silent watchers, Hale's predatory life insurance scheme, and the appointment of white financial guardians — there are signs that a coordinated network is systematically targeting the Osage for their oil wealth. Stace Red Hawk's investigation is hampered at every turn by corruption that reaches from the local sheriff's office all the way to his own supervisor in Washington, and his discovery that Ballard has been reading his mail confirms that no institution can be trusted. Key turning points such as the hidden oil found on Belle's land and the decoy letter designed to expose Hale push the investigation forward even as the walls close in. The two trials strip away layer after layer of the conspiracy, revealing the sheriff's personal role in the plot and the full breadth of anti-Indigenous violence in Watona. Nola's shooting of her husband stands as the novel's most personal turning point, showing how thoroughly the culture of exploitation has made trust between Osage and white people impossible.
