The Zeta Yoke is based on legal documents made available by the government of the state of Coahuila, information submited by the National Human Rights Commission and an exhaustive research of other material.

It focuses on this cartel's control of the Piedras Negrasprision and the brutal reprisals in Allende and other local districts following a betrayal, responsibility for which lies at the door of the DEA and Mexico's Federal Police.
