"It is 2004. After earning a PhD in Physiology, academic prodigy Rebecca Boone Hildebrandt, drawn to Vietnam by her lust for adventure, nears completion of another two-year course of study. Here, her instructor is a master of martial arts and former wartime-era associate of her father.
After drug traffickers expanding their operations force a confrontation with the righteous old man, operatives of the West draw him into another covert war. Thrust from a study of martial arts into their most serious application, Boone joins a face-off against a hardened criminal organization backed by local communist beneficiaries."
