Ironically, the “noble” killer decided to take revenge on those who hired him to kill the child (a 13-year-old Mexican girl). By the way, this girl was traded by his father, whose supply of children for adult entertainment in the United States was the main activity.
The insidious killer is played by Liam Nisson. I was glad that the role was chosen according to his age. And Guy Pearce is an FSB officer who took care of a thirteen-year-old Mexican woman out of compassion and because she was a valuable witness.
The film very fascinatingly shows the revenge of the killer and the hunt of the FSB on the killer himself.
