Ciudad Juárez, Mexico. Two cities. Different sides of the border. They share streets. They share families. But most of all they share crime. And one gang rules over it all: Los Aztecas. In Tequila Sunset , three people are confronted by Los Aztecas's ruthless power: a reluctant gang member, an El Paso police officer, and a Mexican federal agent. As their paths cross with the gang and each other, they all become involved in a complex struggle between law and crime, violence and order, and ultimately, life and death.
