Agent 17 spend her life being surrounded by tall buildings in an unknown place. She doesn't know the world outside the headquarters. Ang alam lang niya, labin walong taon na siyang namamalagi sa Camp Heitron na tahanan ng mga batang wala ng mga magulang.
However, Camp Heitron is not just a typical orphanage. They train children how to combat and to hold guns for their future assignment. Sa madaling salita, inihahanda nila ang mga batang ulila para isabak sa iba't-ibang misyon. Once you become 18, automatically, you will be sent to do your fisrt ever task.
Agent 17 is good, too good that even the higher authority feared her abilities. Few months before she turned 18, Camp Heitron already gave her the most difficult task, and that is to stop the illegal business of Yoggana clan and to kill the couple who brought chaos to Camp Heitron, the Yoggana couple.
