The story shows a man hired as an assassin, and on one of his assignments, he runs into a very young girl, and finds out her dad is the target. We see flashbacks to his childhood, and how he started out. The girl is charming and sweet, and hearing her backstory, it's very understandable why the man is hesitant on completing the mission. It's impossible for this to have a happy ending, and it was very depressing.
