U.S. Customs official Robert “Bob” Mazur (Bryan Cranston) goes deep undercover to infiltrate Pablo Escobar’s drug trafficking scene plaguing the nation in 1986. Teamed with impulsive and streetwise fellow agent Emir Abreu (John Leguizamo) and rookie agent posing as his fiancé Kathy Ertz (Diane Kruger), Mazur befriends Escobar’s top lieutenant Roberto Alcaino (Benjamin Bratt), and navigates a vicious criminal network in which the slightest slip-up could cost him his life.
