Léon: The Professional
(1994)
Léon, the top hit man in New York, has earned a rep as an effective "cleaner". But when his next-door neighbors are wiped out by a loose-cannon DEA agent, he becomes the unwilling custodian of 12-year-old Mathilda. Before long, Mathilda's thoughts turn to revenge, and she considers following in Léon's footsteps.
Two children, Ignacio and Enrique, know love, the movies and fear in a religious school at the beginning of the 1960s. Father Manolo, director of the school and its professor of literature, is witness to and part of these discoveries. The three are followed through the next few decades, their reunion marking life and death.
