Vincent Coangco, a battle-hardened modern military veteran and a scholar of Philippine history, finds himself transmigrated into the year 1898. He occupies the body of Carlo Valdez, a legendary sharpshooter within General Antonio Luna's inner circle (Campo de Aide). Despite his elite skills, Carlo possesses delicate, feminine features that lead the "Boy General," Gregorio "Goyo" Del Pilar, to believe he is a woman disguised as a soldier.

Major Lucas Astor, a decorated modern-day tactical expert, dies in a high-stakes counter-terrorism raid only to wake up in 1892 Manila. He inhabits the body of Celistino Tianco, a frail-looking warehouse clerk and secret member of the newly formed Katipunan. Using 21st-century military doctrine and historical foresight, Lucas (as Tino) rises through the ranks to become the "Ghost Strategist" of the revolution. The story follows his struggle to save the "Supremo" Andrés Bonifacio from internal betrayal and his unexpected, persistent pursuit by the young, dashing Gregorio "Goyo" Del Pilar.
