In 1980, at the Hongxing Machinery Factory in Yanzhou, female worker Lin Xiumei publicly flips the table in protest against the gender discrimination in the distribution of New Year goods, catching the attention of He Zhenbang, the factory director's son. After Lin Xiumei is driven out of her family home for protecting her abused niece, she and He Zhenbang rush into a marriage to put an end to the rumors. After their wedding, she breaks the traditional stereotype of women silently enduring hardship. With her formidable technical skills and fiery personality, she stands up to her troublesome stepmother-in-law and gradually wins over her resistant stepdaughter. She not only leads the female workers in demanding equal pay for equal work but also joins forces with her husband to overcome technical renovation challenges. Ultimately, she exposes a corruption conspiracy and receives the National May 1st Labor Medal, achieving remarkable success in both her career and family life as a woman of the 1980s.
