When a 12 year old girl becomes under protection of a hitmen, she must learn the tools of the trade to avenge her parents assassinated by gangsters.

When gangsters kill her parents, a 12-year old girl finds protection and a mentor in a hit man who agrees to her demand to be taught how to get revenge.
