La Femme Nikita (1990)

An urgent life-or-death dilemma befalls Nikita--the feral street girl and violent drug addict--after killing a police officer at point blank. Hopeless, Nikita is given a new lease of life, when she reluctantly exchanges her doomed fate for a secret government program that promises to mould her into a cold-blooded assassin under the wing of her sadistic mentor, Bob. Now--with a new set of skills, a new identity, and lethally sophisticated looks--Nikita is the ultimate weapon and the perfect puppet for doing the government's dirty work; however, what happens if this trained killer chooses love over death?
