Navajo sleuths Joe Leaphorn and Jim Chee are hot on the trail of Butch Cassidy. A drunken Navajo shaman is holding the murder weapon near the scene of a cop killing, but Chee has a hunch he's innocent. Their legwork turns up a CIA spook, a giant coded message, and a century-old bank heist proving that Butch Cassidy didn't die like they say in the movies.

In Season Two, Lt. Joe Leaphorn reunites with Jim Chee, his former deputy turned private eye when their separate cases bring them together in pursuit of the same suspect. They find themselves in the high desert of Navajo Country chasing a killer.
