Reservation "bad boy" Thomas Begay is found dead-drunk under the La Plata Bridge, which is not unusual for him. What is unusual, however, is that beautiful BIA investigator Patsy Greyhorse is found lying beside him, not drunk, or even a Navajo, but very dead nonetheless. Charlie Yazzie, fresh from law school, risks his career and even his life to help his old friend.
The answer seems to lie with the Yeenaaldiooshii . . . should one choose to believe in such things.
