Finn Chandler, a top elite from Skynet, takes a job as the personal bodyguard of Sloane Lee, CEO of Huhai Shenghe, to track down clues of the Plum Blossom Mark linked to his sister's disappearance. Sloane Lee holds the latest Divine Phoenix Chip, and is targeted by Holt Hawthorne and Zane Lowe one after another, with various assassins and martial arts experts launching successive attacks. Finn repeatedly defends the Lee sisters with his hardcore combat skills, silver needles and firearms, recruits assassin Phoenix, and outmaneuvers Zane Lowe and The Poison Master. Yukina Sato from overseas sends ninja Chiyo to infiltrate and assassinate, but all conspiracies are crushed by Finn. During their confrontations, Finn reveals his Skynet identity, but he and Sloane have long developed mutual affection, deepened by a one-night encounter. After all the villains including Sato and the Hong group are arrested, Finn plans to leave after completing his mission, but Sloane confesses and asks him to stay with her for life.
