The film follows the story of Léon, played by Jean Reno, a professional hit man for an Italian Mob crew run by Danny Aiello. He lives next door to a ferociously independent 12-year-old girl named Mathilda - played by then newcomer Natalie Portman, whose father is involved in drugs and crooked cops. One day, a crew of the cops - lead by Gary Oldman in an over-the-top performance - kills her entire family while Mathilda is out buying groceries. Taking pity on her, Léon hides her in his apartment when she returns to save her life. Mathilda learns of Léon's hit man profession and decides to follow in Léon's footsteps as a 'cleaner.' She then falls in love with him and manages to reawaken emotions within Léon he has kept locked away as part of his profession. Good writing, and two well palyed roles.
