A bank robbery has left an officer down and a suspect on the run. Law enforcement is in hot pursuit, and residents are on the lookout—but before anyone can catch the criminal, tragedy strikes.

A member of the Taos Pueblo tribe has been shot and killed. The culprit? An untraceable 3D printed gun. With the support of fellow tribal cops, Eva "Lightning Dance" Duran breaks the news to the victim’s family and swears to find justice.

More violence follows, feeding the rising racial tensions between the Taos Pueblo people and the Hispanic community. New evidence forces Eva to consider the possibility that the bank robbery and 3D guns are related, but until she figures out how, there’s no telling how deep this crime ring goes…or how far its evasive ringleader will go to protect it.
