Cocaine, money laundering and murder are returning to Netflix in 2018 with Season 4 of Narcos. The network announced the new season in a 40-second teaser video, featuring a mariachi band, a shower of powder and the memorable theme song, "Tuyo," by Rodrigo Amarante.

Narcos will return in a new country, Mexico. The season will focus heavily on the notorious Guadalajara Cartel, founded by Rafael Caro Quintero, Miguel Ángel Félix Gallardo and Ernesto Fonseca Carrillo in the 1970s.

The first two seasons of the series followed the infamous Colombian drug kingpin Pablo Escobar, played by Wagner Moura; Season 3 focused on another Colombian crime empire, the Cali Cartel.

Along with a new setting and cartel, the series will introduce a different cast, including Michael Peña (Crash, American Hustle) and Diego Luna (Rogue One, Y Tu Mamá También). Netflix did not reveal which members of the Guadalajara gang the actors will play.

Season 4's move to Mexico means the actor Pedro Pascal, who starred in the first three seasons as Drug Enforcement Agent Javier Peña, won't be prominently featured. However, during an interview with The Hollywood Reporter on Tuesday, showrunner Eric Newman said that the location change doesn't necessarily mean he won't make an appearance. "It was a part of the plan as early as Season 2 [to remove Peña from the storyline]. The design was always to finish out the Colombian story and the players that we've come to know there, and start anew in Mexico," Newman said.

Details on the show are limited, and a streaming date has yet to be set. But one thing is certain: There will be drugs, action, blood and lots of money. The history of the Guadalajara Cartel is violent.

"Everything about Mexican trafficking is closer to home. The proximity, the complexity of the relationship between the two countries. Colombia is a sort of remote place to most Americans, who have never been to Colombia or met a Colombian. It was easier to distance ourself from who we thought were the enemy. Mexico is our neighbor and so the ties are deeper," Newman said.

One of the first major organized Mexican drug gangs to pump heroin and marijuana into the United States, the Guadalajara Cartel was also known for its friendly ties to Colombian cocaine mafia rings, which resulted in multibillion-dollar profits for both groups. It was the top Mexican drug caretl until 1985, when the gang was accused of the murder of U.S. DEA agent Enrique "Kiki" Camarena. The fallout from that ended their criminal network.

In 1989, the cartel's most prominent co-founder, Gallardo—referred to as "El Padrino," or the Godfather—was arrested in Mexico, where he is still being held in custody. In August, Gallardo was officially charged for the deaths of Camarena and a Mexican pilot, Alfredo Zavala. He was ordered to pay the victims' families $1.18 million in reparations, according to the Los Angeles Times.
