Ethan, a top-tier agent codenamed Zero, is unexpectedly hired as a bodyguard by Aurora, a seven-year-old orphan from a ten-billion-dollar trust, for "one dollar a day." Aurora's parents were murdered; to swallow her hundred-billion inheritance, her cold-blooded relatives and the "Shadow Consortium" behind the scenes have put a sky-high bounty on her head on the dark web! For the sake of this one-dollar contract, Ethan transforms into a merciless grim reaper, standing alone against an entire city of killers, elite mercenaries, and deep-web cleaners. From bullet-streaked alleyways to glittering financial summits, he mercilessly tears apart the consortium's hypocritical masks, sending every power player who covets the girl to hell! "An agent never breaks his contract. Her life — you scum can't afford it!"
