After her husband dies unexpectedly, Lin Wan works tirelessly to support her family on her own. Her mother-in-law, Wang Cuilan, and sister-in-law, Liu Jiajia, forge documents in an attempt to transfer the couple's marital home into a dowry. Lin Wan produces proof of her down payment and hires a lawyer to register a property dispute. She then makes a living selling braised meat at the night market using her family's ancestral recipe. The mother and daughter, resentful of her, hire thugs to wreck her stall and maliciously report her for allegedly adding banned substances to her braised meat. Meanwhile, a competitor named Zheng Dalong hires people to bring a dead rat to her stall and frame her in an attempt to steal her customers. Lin Wan records everything on surveillance cameras, gathers evidence, and works with the police and market regulators to pursue legal action. All the wrongdoers are held accountable, forced to pay compensation, and detained. Lin Wan expands her business, reclaims her home, and builds a stable, happy life with her son.
