Shen Suxin spent eight years pouring her heart and soul into building the Song family's thriving old braised broth shop, but her in-laws teamed up with her husband Song Zicheng to secretly alter the property rights, attempting to seize her hard work and braised broth recipe. Holding onto the core master broth, she angrily broke ties and left the Song family, starting anew at Erdao Lane with her younger sister Shen Xiaonuan. Unwilling to give up, her in-laws forged an IOU to freeze her accounts, colluded with Chamber of Commerce leader Luo Wanshan to implement a raw material blockade, and even sent people to stir up trouble and maliciously counterfeit her products. Gathering complete evidence with the help of Zheng Dachuan and others, Shen Suxin broke through heavy suppression, using the law to expose their entire conspiracy of forging documents and making profits through counterfeiting.
