Shen Wanqing was once an unparalleled strategist on the modern battlefield, full of honors, but was betrayed and assassinated by his first love teammate Zhou Jun during an international anti-gang operation. The two traveled back to 1983 together. Shen Wanqing became a doormat in the village of the same name. She was framed by her sister and forced to marry Lu Zhanbei, a special forces instructor who retired due to injury, disabled both legs and had a gloomy personality. Shen Wanqing relied on modern wisdom and military literacy to build a career, manage her husband, and fight for the best in the 1980s, while secretly investigating the truth about time travel and her former enemies. When history reappeared, she joined hands with Lu Zhanbei, who had stood up again, and started their own "anti-gang war" on another front in the wave of reform and opening up.
