Qiao Xin encounters danger while diving. Struggling ashore, she returns home to find her mother lying on the ground with a head injury. Her husband Shen Ze and mother-in-law force Qiao's mother to press her handprint onto a property transfer document. Qiao Xin rushes forward but is knocked down by Shen Ze, who then approaches her with a knife. The doorbell rings, and as Qiao Xin tries to call for help, her mother-in-law strikes her head with a vase. Semi-conscious, she sees her best friend Jiang Weiwei enter. Qiao Xin weakly crawls out, hoping Jiang Weiwei will save her, only to discover that Jiang Weiwei and Shen Ze have been conspiring together for a long time, coveting the Qiao family's assets. Everything is exposed to Qiao Xin. After forcing Qiao Xin to transfer the last of the Qiao family's property to Shen Ze, he grasps Qiao Xin's hand and uses it to stab Qiao's mother to death. The three then drag the breathless Qiao Xin into the sea, faking her accidental death after murdering her mother. The next day, news reports Qiao Xin's death, and the two conspirators are relieved. However, Qiao Xin is not dead; the news of her death was released with the help of her childhood friend, Ji Jinnian. Filled with hatred, Qiao Xin is determined to seek revenge. After a year of preparation, Qiao Xin's identity has become Ji Jinnian's sister, Ji Yao. After carefully dressing up, she stands in front of the mirror and writes "blood for blood" with lipstick, then resolutely leaves despite Ji Jinnian's pleas.
