Moses and Sera work together to help the Acholi people of Northern Uganda, refugees caught in the middle of the Lord's Resistance Army insurgency in Acholiland.

Disturbed by these nightmares, the violence surrounding the field hospital and his treatment of various injuries caused by the fighting strip away his deteriorating moral compass.

He finally breaks, running from a hospital camp in response to the alleged rape of a girl, where he comes in to contact with child rebel fighters.

He disarms and kills one, finally shattering his pacifist beliefs, which causes him to take a rock and self-mutilate his face in a violent delirium.

Moses takes it upon himself to rescue the remaining twenty, and ends up murdering even more child militants in the process, using some innate combat skills that he fails to understand the source of.

Moses' rage at the corrupt systems at play in Uganda cause him to seek to destroy the Lord's Resistance Army and kill Joseph Kony, and the alter ego seizes upon this as a war for him to fight.

It is only when a group seeking to assassinate a famous American actress and humanitarian, Margaret Wells, reaches Moses through Jack do the two finally cooperate.

Though Moses' operation is successful, he is unable to reconcile his killing of innocent civilians with Sera and his past life, and leaves her behind once again to continue his battle against the LRA.

After smuggling out a family besieged by raiders from their hiding spot on a hill, Moses makes a last stand there, fighting against scores of armed herders.

However, Moses' exposure to violence in his medical camp effective triggered his combat conditioning, and his alter ego emerged as the next "Unknown Soldier", discarding morality to engage in eternal warfare.

The Unknown Soldier, still locked in to war with Joseph Kony, confronts Sera once last time, finally telling her the man that she knew as Moses was completely gone.

Sera appears, telling the Soldier/Moses that no matter who he is, she always loved him, and the two embrace; however, this pleasant vision is a dream, and it is shown that he had actually been shot in the head before ever reaching Kony.

In a symbolic conclusion of his morality arc, it turns out that he didn't kill a single person in Kony's camp, instead throwing its garrison of child soldiers in to disarray, who assume there is a much larger force due to a huge amount of diversionary gunfire and explosives.

In the epilogue, Sera remarries to a Muslim journalist who had covered the exploits of her husband as the Unknown Soldier: the two have several children and live as a family.

Kony, true to events at the end of the story's publishing in 2010, is shown to have been pushed out of Northern Uganda, but still active in certain areas in Africa.
