Forsaking his idealist past, Tanthai has become the Thai underworld's secret weapon: A remorseless contract killer able to dispatch any target... provided his price is met. But when Buem, a Machiavellian politician, hires Tanthai to eliminate an upstart drug kingpin threatening Bangkok's fragile criminal status quo, the lone wolf assassin's ethical vacuum is inadvertently breached. Caught between rival Triad bosses, mercenary policemen and power hungry parliamentarians, Thailand's deadliest assassin becomes the country's most wanted target. As Bangkok boils over into a full-fledged gang war, Tanthai crosses gun barrels with a rival from out of his past and risks everything to answer a conscience he thought he'd long ago erased.
