Zhao Pan'er (Liu Yifei), who runs a tea shop in Qiantang, is shocked to hear that her fiancé, the new top scholar Ouyang Xu (Xu Haiqiao), is going to marry the daughter of a high-ranking official. Unwilling to accept her fate, she vows to go to Beijing to seek justice. On the way, she meets Gu Qianfan (Chen Xiao), the commander of the Imperial City Division, who comes from a powerful family but is upright by nature, and is involved in a major case in Jiangnan. The two get to know each other and thus become friends. With her wisdom, Zhao Pan'er rescues Song Yinzhang (Lin Yun), the "first pipa master in Jiangnan" who was deceived into marriage and was abused, and Sun Sanniang (Liu Yan), the generous cook who was forced to run away from home by her harsh family. The three sisters have since traveled together and finally arrived in Bianjing to see the prosperity of the world. In order to avoid being driven out of Tokyo by Ouyang Xu who was trying to marry someone else, Zhao Pan'er, Song Yinzhang and Sun Sanniang went through hardships together and developed the small teahouse into the largest restaurant in Bianjing step by step. They exposed the true face of the unfaithful man, gained each other's sincere feelings and insights into life, and opened a door to equal redemption for countless ordinary women.
