What's it like to be an employee of a global drug-trafficking organisation? And how does a 15 year old American boy go from star quarterback to trained assassin, surging up the cartel corporate ladder? At first glance, Gabriel Cardona is the poster boy American teenager: great athlete, bright, handsome, and charismatic. But the streets of his border town of Laredo, Texas, are poor and dangerous, and it isn't long before Gabriel abandons his promising future for the allure of the Zetas, a drug cartel with roots in the Mexican military. His younger friend Bart, as well as others from Gabriel's childhood, join him in working for the Zetas, boosting cars and smuggling drugs, eventually catching the eye of the cartel's leadership. Meanwhile, Mexican-born Detective Robert Garcia has worked hard all his life and is now struggling to raise his family in America. As violence spills over the border, Detective Garcia's pursuit of the boys, and their cartel leaders, puts him face to face with the urgent consequences of a war he sees as unwinnable.
