Qin Yan was originally the daughter of anti-drug hero Qin Zheng. Later, Qin Zheng unfortunately died in an operation and entrusted his daughter to his friend Gu Yi. Little did he know that the failure of the accident was caused by Gu Yi, who happened to be Gu Lin's second uncle. Gu Yi secretly trained Qin Yan to become a killer. Qin Yan became the boss of underground trading, and he also had an identity that he didn't know about. Gu Yi accidentally discovered that his nephew Gu Lin's identity was not simple, so he designed Qin Yan to mistakenly think that it was Gu Lin's father who had killed him. They were the same person ten years ago, so the two quietly plotted the real murderer behind the scenes, and finally succeeded in fulfilling Qin Zheng's last wish. Gu Lin also fulfilled his mission and became the core figure of the Dark Night Drug Enforcement Team... In the end, they carefully designed a grand wedding for Qin Yan, but they didn't know that it was a bigger conspiracy. Qin Yan abandoned him, and the two met again on a fighter plane heading to S country...
