The border is a tough place to work, especially for FBI agent Tom Eriksen. With a history of violence, he cannot afford any on duty screw ups. So when an investigation ends in a bloody shootout and the shooting is deemed "questionable," the bureau reassigns Eriksen to an office known as "the Island of Misfit Cops", a resting place for those who have screwed up enough to warrant being dumped in El Paso, Texas. But when his partner is murdered, Eriksen must take charge and solve the case, wading through corruption and betrayal to discover the truth.
