Pablo Escobar (1949-1993) was an infamous mobster who ran Colombia’s Medellin drug cartel with an iron fist. During his reign, Escobar controlled about 80 percent of the global cocaine market, and took in about $70 million/day.

To maintain his power, the ruthless kingpin had his henchmen assassinate thousands of adversaries, including policemen, politicians, witnesses, judges, and journalists. Therefore, to infiltrate the ranks of such a vicious operation at its height in the 80s was certainly a very difficult and dangerous undertaking.

However, the risks didn’t deter U.S. Customs Agent Robert Mazur (Bryan Cranston), even though he had a wife (Juliet Aubrey) and two children (Lara Decaro and Niall Hayes). Robert assured his spouse that this would be his last assignment before retirement. He adopted the alias Bob Musella and pretended to be a shady Tampa businessman who was willing to turn the drug cartel’s drug money into Florida real estate.

He recruited two agents to help him bring off this daring sting. One was Kathy Ertz (Diane Kruger), a novice who posed as his fiancée on her first undercover case. The other was Emir Abreu (John Leguizamo), a new partner who has street smarts. Soon the trio is swept into a seedy underworld where they have a close brush with death at every turn. However, by proving themselves to be capable and trustworthy money launderers, they gradually work their way up the Medellin cartel food chain to the point where they gain the confidence of Roberto Alcaino (Benjamin Bratt), Escobar’s Miami-based right-hand man.

Consequently, Bob and Kathy become friends with Roberto and his wife, Gloria (Elena Anaya). They are regularly invited over for dinner to the Alcainos’ sprawling mansion, however, the host always reminds Bob and Kathy about the gruesome fate that awaits snitches and traitors.

Thus unfolds The Infiltrator, a riveting, cat-and-mouse thriller directed by Brad Furman (The Lincoln Lawyer). The screenplay was adapted by Furman’s mother Ellen from Mazur’s memoir of the same name. The film stars Bryan Cranston, who ratchets up the tension by portraying his conflicted character with a convincing combination of arrogance and existential dread.
