P able Escobar is gone, but the drug war rages on! After three seasons in Colombia, the suspenseful series moves the action to Mexico for Season 4. The rise of the Guadalajara cartel in the 1980s is chronicled via two key characters on different sides of the law. Kiki Camarena ( Ant-man and the Wasp’s Michael Peña) is an ambitious DEA agent who moves his family from Fresno, Calif., to Mexico in hopes of making an impact; Félix Gallardo ( Rogue One: A Star Wars Story’s Diego Luna) is an aspiring drug lord who uses risky alliances (rival cartels, corrupt cops) to expand his empire beyond Mexican marijuana by moving Colombian cocaine into the U. S. Cleverly, when we first meet each character in their separate — and equally intense — introduction scenes, it’s Kiki who’s negotiating a drug deal (he's undercover) and Félix who’s serving as a cop in a uniform and badge. Expect more blurred lines as the events that led to the complex mess that is the drug war are explored on this dangerously addictive drama!
