Two modern best friends accidentally travel through time together, one becoming the Zhou family daughter-in-law Xu Zhi, and the other becoming her own mother-in-law Song Xiaoman (Liang Guixiang). As soon as they wake up, they encounter the husband's family planning to misappropriate the daughter-in-law's dowry. The two quietly recognize each other and form an alliance. They argue logically, clarify the shop's property, and insist on dividing the family, with Song Xiaoman determined to end her old marriage. Moving out of the old house to live independently, the two face the husband's family's harassment head-on, relying on reason and confidence to fight for their own lives and dignity.
