A smart, scrappy teacher is called upon by her traditional Mexican-American grandmother to help a relative in Mexico escape the clutches of a dangerous cartel. Reluctantly, she agrees, but in coming to her grandmother's aid, she needs the help of The Hated One, an ex-fiancé who broke her heart years before. Together, they must devise a plan to rescue her desperate, long-lost cousin and her cousin's child. To do so, Dina Salazar must enter the dreaded turf of the Zetas, a ruthless Mexican drug cartel. Such a mission is not for the faint of heart!
