In the beginning scene of the movie, many young boys are trained from an early age in hand-to-hand combat, using firearms, and many other combat skills, in order to become professional, international hitmen for hire by the organization that sends men to train and raise them. They are also raised to become very well disciplined and emotionally detached from anything that they do in order to accomplish the objectives of their mission.
