On her third birthday, her father, Jiang Wenxuan, blamed her for the blood from her mother's car accident. When she was twelve years old, her stepmother Chen Feng cut off the swing rope left by her mother, and she was completely kicked out of the house. Ten years later, Lin Muxue is no longer an orphan waiting to be loved. Under the protection of kind Aunt Zhang and a group of "family members" who have their own scars but depend on each other - retired undercover Yang Fan, hacker twin Lin Xilinyue, military commander Peng Peng, intelligence master Ding Feng, and doctor Zhang Xiaoya, she grew up to be the leader of "Yunxue", a top intelligence team that wanders in gray areas. When his father's company "Xuanyun" falls into a strange crisis, He Chengxi, the leader of the city's economic investigation detachment, brings dangerous cooperation: an international criminal group code-named "Melting Pot" is trying to devour "Xuanyun" as a money laundering tool. In order to protect her mother's last wish and innocent employees, Mu Xue returned home brazenly in the name of heir, setting off a storm of seizing power amidst the cold eyes, frame-up and betrayal of her father again. However, the truth she uncovers is far crueler than imagined. The premature death of the mother, the weakness of the father, and the greed of the stepmother are all controlled by a pair of elegant and cold hands - the "Mr." In the shadow, and his intricate drug manufacturing, drug trafficking, and money laundering empire. The old hatred of the broken string of the swing turned out to be the tip of the iceberg of a huge conspiracy. This is a revenge that spans twenty years and is also the ultimate trial of blood and sin. When all the clues point to the darkest moment before dawn, Lin Muxue must join hands with He Chengxi and lead her "family" to cut off the poisonous chain and pry open the dark curtain amidst gunfire, data and the fog of people's hearts, to bring justice to the dead and win a new dawn for the living.
