Su Manqing, a famous actress in Shanghai, was forced to marry into the Lu family, a wealthy military and political family, and became the wife of Marshal Lu Zhengyan three years ago in order to resolve the family's opium smuggling case. On their wedding night, Lu Zhengyan received an anonymous secret letter, accusing Su Manqing of being an informant planted by a competitor with the intention of stealing military and political secrets. In a rage, he concluded that Su Manqing was greedy for wealth and betrayed him. Regardless of her defense, he drove her out of the house with a divorce letter. The Su family also fell into rapid decline due to the loss of asylum. Three years later, Su Manqing returned to Shanghai as an underground worker "Nightingale" and was ordered to lurk next to Lu Zhengyan, the director of the Pacification Office, to obtain the Japanese defense map. The two met again. He was a powerful superintendent, and she was a social butterfly who dealt with all forces. The love and hatred of the past were intertwined with the current mission. She had to beware of his temptations and avoid the pursuit of the Japanese special high school. The truth about her "collaboration with the enemy" back then was gradually revealed in each confrontation.
