In the late autumn of 1938, cold rain fell on Nanjing in the occupied area.
Zhong Wanyi, a doctor who returned from studying abroad, clutched the secret message in the pocket of his white coat. The copper stethoscope glowed coldly under the bayonet of the Japanese army's interrogation. She was ordered to succeed her deceased brother and establish a secret radio station in the basement of Drum Tower Hospital. The "Nightingale" she contacted was actually the man in a long gown who always came to pick up medicine late at night - Midsummer.
No one knew that this translator who worked in the Wang Puppet Government had information written in rice vinegar hidden in his briefcase; no one had ever seen him using a brush dipped in blood to draw Japanese defense plans on a boat on the banks of the Qinhuai River. When Zhong Wanyi's scalpel opened the bullet hole of the seventh wounded man, Midsummer was hiding potassium cyanide in the tea cup for the Japanese officer, and his fingertips were still stained with ink from the translation document.
They exchanged secret codes in the smell of formalin in the autopsy room, broke out back-to-back under the searchlights of the Japanese army's massive manhunt, and guarded the same secret in the city's beacon fire: the coordinates of an arsenal recorded in the cracks of the Diamond Sutra. But when Zhong Wanyi discovered that her brother's sacrifice was related to Shengxia Li's "betrayal", and when Shengxia Li had to personally send her to the prison of the Japanese army's special high-tech department, the gown soaked in gunpowder smoke finally became a bandage wrapping each other's scars.
"Live." These were the last words he said to her before the execution ground, like a seed buried in the scorched earth. It was not until three years later that Zhong Wanyi was in the medical team in the liberated area and saw a note written in Chinese in a captured Japanese army diary: "Wanyi's stethoscope knows how to suture a nation's wounds better than my pen."
