In the late 1980s, Song Yunzhi, the head of the machine repair group at the Red Star Textile Factory, fierce and outspoken, forcefully pulled the main switch to save a fellow worker, reuniting with the new factory director Gu Hong'an after more than ten years. The two upheld justice to thoroughly investigate production hazards, while facing wave after wave of life's storms: her maiden family forcing marriage and banishing her, her mother-in-law and eldest brother coming over to fight for a house, and the acceptance estrangement of the two children. Through several collisions and standing by each other, the family unlocked their knots and grew individually, setting their hearts in one place amidst the bustling years, weaving a stable and warm good life.
