A courier containing methamphetamine disrupts the life of white-collar Tan Doudou. The sender is Jin Yuan, her boyfriend who escaped from marriage seven years ago. Tan Doudou escaped from the police and went to the seaside to look for Jin Yuan. At this time, Jin Yuan was being suspected by the police of using the auction to launder money for the drug cartel, and Tan Doudou still wanted to persuade him to turn back. In fact, Jin Yuan was an undercover agent placed by the police in a drug cartel. He could only deliberately keep Tan Doudou indifferent, hoping that she would stay out of danger, while at the same time dealing with the many temptations of drug dealers. In addition, police officer Qiao Liang discovered that his girlfriend's father, Team Huang, was a spy. In the end, Jin Yuan and the anti-drug brigade paid a bloody price and successfully destroyed the drug trafficking group.
