The story of the soldiers of the 4th Infantry Division of the Philippine Army and their actions during combat. Through multiple perspectives, the story focuses on these soldiers, mainly: Alex Marasigan, an IT expert who quits his desk job and joins because just like his brother, he wants to serve the country, Abraham "Abe" Kamlun, a Tausug Muslim man, who, despite his family's opposition of the move, joins the Army nonetheless, and Michael Mendoza, a boy who joins the Army to provide for his family.
