Modern elites Qiao Ran and wealthy heiress Xia Xiaoqi accidentally travel back to 1978 in Gegeshi Village, where they become sisters-in-law in the Lu family. In the original novel, they are tragic supporting female characters: Qiao Ran will throw herself into a river because of infidelity, while Xia Xiaoqi will be sold off and fall off a cliff. But the two refuse to accept their fate and join forces to fight against their harsh mother-in-law, Liu Chunhua, and their divisive sister-in-law, Lu Hongli, while cleverly thwarting the schemes of scumbags like Cheng Fangyuan. Along the way, they each attract the affection of the gentle and refined Lu Xiangnan and the outwardly cold but inwardly warm Lu Yanbei. They also inspire their mother-in-law to change. In the end, they rewrite their destinies, find love and family affection, and embark on a happy new life.
