Modern-day best friends Shen Xiaoya and Su Tang accidentally travel back to the 1970s and 1980s, becoming the two daughters-in-law of the Gu family. Shen Xiaoya, a lively, carefree girl who loves singing and dancing, finds herself married to Gu Zheng, a cold and reserved military man. Meanwhile, the capable and spirited Su Tang meets Gu Huai, a refined and gentle doctor. Together, the two women take on troublesome relatives, resolve conflicts between mothers-in-law and daughters-in-law, and launch their entrepreneurial journey by selling luosifen, a famous river-snail rice noodle dish. As the tides of the times sweep forward, they break free from outdated conventions. One pursues her dream of attending university, while the other builds her business. Along the way, they find family bonds and love, living extraordinary lives of their own.
