When Marroquin reunites with his son Lucas, he realizes that being a father is more difficult than running a criminal empire. Becerril and his elite unit realize they have underestimated their opponent. The effects of the US Army secret experiment keep spreading.
To avoid extradition, the charismatic and unpredictable drug lord, Alonso Marroquandiacute;n, escapes prison in Mexico to hide in the middle of the desert. While on the other side of the border, a United States Army experiment with pigs in a military base, goes wrong and the Mexican police unit going after Marroquandiacute;n gets infected, transforming into a new breed of zombies with special abilities. The army and this new species converge in Marroquandiacute;n's hideout, where the battle for survival begins.
