Cal is a hitman on the run from his powerful old boss. He has found sanctuary among the invisible poor in the barrio outside of Mexico City. He lives in and fixes up an old, dilapidated Catholic church, which is how he earned his nickname among the locals as "El Padre." The Father. The Priest.
After a young Mexican woman who he befriends is trafficked to a crime organization in Los Angeles headed by his old boss, Cal must come out of hiding to rescue her and, at the same time, face his dark past.
