Twelve years have passed since Sofia De Luna's mother was murdered. Sofia now leads a quiet life in Chicago, far from the cartel violence she was raised amidst. But when her narco father's retirement catapults her to head of the family, that peaceful existence is upended. Unhappy with this changeover of power, Sofia's brothers and cousins are wary of her desire to legitimize the family and her insistent questions about her mother's mysterious death. Meanwhile, in Mexico's uncertain political climate, Andres Herrera, the ex-sicario accused of Sofia's mother's murder, sees the opportunity for his exit from the drug business. He just needs Sofia, his first love, to uphold the truce between the cartels before the war brewing at the border trickles down to Mexico City, marring the upcoming election. After a chance meeting with a disenfranchised DEA agent reveals the true depths the Torres will go to keep their power, Sofia decides she must stop the war her cousins have put in motion. But if she sacrifices her family for the dream of peace, will she meet the same fate as her mother?
