1943, Shanghai. At the Garrison Headquarters Hospital, the smell of disinfectant water persists all year round. Qin Lan is the most inconspicuous head nurse in the whole hospital. She speaks softly and is always gentle and gentle. No one knew that every time she pressed her pulse, every time she changed her dressing, every time she adjusted her quilt, she was conveying information. The ink dots on the body temperature sheet are passwords, and the creases on the medicine bottles are secret codes. She does not need a gun or a knife, but only uses one pair of hands to support the entire underground transportation line under the eyes of the enemy. The secret service team searched the entire hospital and checked every document, but they never suspected the nurse who always lowered his head. They don't know that the sharpest knife never needs to be unsheathed. It is a high-intelligence game throughout, with no romance line, and a drama quality.
