A Mexican hit man is a "sicario." Drug action on the Texas border.

Rating: Null/10 (9 January 2016)

This is a tight thriller and all the actors/characters are interesting. A "sicario" is Spanish for "hit man" and in a fashion the whole movie is about one hit man who is doing it all for himself.
Emily Blunt is FBI agent Kate Macer and in the open scene we see her and her team discovering a cache of bodies behind walls, then an explosion as her men open a chamber in the ground. Back in the office she is concerned she may face discipline but instead she is asked if she would be willing to accompany a team searching for tunnels and illegal drug movement across the US-Mexico border.
The whole operation seems mysterious, to us the viewers and to Kate. She isn't told much, she is told to "observe and learn", while a larger group gets their orders for a mysterious trek into Juarez to bring back a prisoner. They really only wanted her to be present, as a way to make it legal for them to cross the border. They had no intent that she actually participate.
Josh Brolin as agent Matt Graver is the team leader and he always seems to be too relaxed for what is going on. The real protagonist- antagonist is Benicio Del Toro in a super performance as Alejandro. He had been an attorney in Colombia but one particular Mexican drug lord had killed and beheaded his wife, then killed his daughter, and he was bent on revenge. He became his own personal "sicario."
The movie is very well made with a number of tense scenes.
SPOILERS: The group confronts a number of Mexicans who had crossed to get information on where the tunnels were. They set up a nighttime sting and Alejandro held hostage a dirty Mexican police officer, together they tracked down one of the drug lord's men, then forced him to take Alejandro to the man's house, where he systematically killed each guard then confronted the family at dinner. After the drug lord smiled and explained to Alejandro that it had only been "business" Alejandro shot each young son and the wife, all at the table, then shot the drug lord. His revenge complete.
