Watch Bryan Cranston Go Undercover in the First Trailer for The Infiltrator

Bryan Cranston is no longer running from the narcs—now he is one. Or rather, the Breaking Bad alumni plays one in The Infiltrator, a crime drama based on the story of a federal agent, Robert Mazur, who went undercover in a major sting operation to bust Pablo Escobar’s Medellín drug cartel beginning in 1986.

The first trailer for the film—the script for which was adapted from Mazur’s autobiography—finds Cranston with a new partner (John Leguizamo), a new fiancée (Diane Kruger) and a new best friend: Escobar’s top lieutenant (Benjamin Bratt). The real-life Mazur spent five years posing as a money launderer, gathering evidence that would ultimately lead to the indictments of dozens of criminals and the collapse of a major money-laundering bank.

The Infiltrator hits theaters on July 15.
