When a sheriff's deputy is found murdered on an Indian reservation, Crews and Reese find themselves in the middle of a turf war between Tribal police and the county sheriff's department. The detectives learn the victim was not well-liked on the reservation and the opening of a new profitable casino may have led to the deputy's demise. Meanwhile, Crews attends a fundraiser thrown by Mickey Rayborn, one of the individuals Crews believes was involved in the conspiracy against him.

When three Russians, including an engineer, are found dead the investigation leads Crews and Reese to Russian mobster Roman Nevikov who Crews believes is somehow linked to his own case. Meanwhile, Crews shoots an intruder who turns out to be someone he knows very well and Reese falls back into old habits.
