Luc Besson - La femme Nikita (1990)

Convicted felon Nikita, instead of going to jail, is given a new identity and trained, stylishly, as a top secret spy/assassin.

Nikita is a young lady who with two Nihilist friends commit robbery and murder while on drugs. After her trial she is not executed or taken to prison, but to a school for special operatives. She is told that Nikita no longer exists and she will be trained to pay back society for what she has done, as a spy/assassin. She is trained for over two years and with no warning is handed a gun in a restaurant and told to kill the man at the next table as her handler leaves.
