Marcus Jones, a top-tier powerhouse known as the Pluto, returns to the country under a marriage contract to protect Chantal Lawson, the CEO of the Lawson Group. Upon his first encounter with Shayla Anson, captain of the National Security Bureau, he reveals a glimpse of his true identity, and the two unexpectedly share a one-night affair. At a restaurant, Marcus fends off the international assassin Mary, exposes Briana Shelton—Chantal's close friend—as a mole, and repeatedly foils the Harrison family's assassination attempts and business schemes aimed at seizing an anti-cancer project. Facing sniper attacks head-on, subduing Draco of the Axes, and effortlessly crushing the assassin, the Dog, Marcus proves himself an unstoppable force.
