In the heart of the military academy of the United Nations Space Command (UNSC), a group of cadets trains to become the next generation of soldiers of this war against the insurgents of the colonized planets. Among these cadets, we find Thomas LASKY who fights his doubts as to the relevance of this war and his fear of not being up to the hopes placed in him. As he prepares to become a great military leader, the alien alliance of the Covenant comes to upset everything. Very inspired by the life of the Master Chief, he must discover what it means to be a hero.
