Li Zheng and Meng Tian have been dating for two years. During National Day, he takes her back to his hometown in Gongshan to meet his father, Li Daming. Li Daming grows suspicious and firmly opposes their relationship. Meng Tian's behavior becomes increasingly bizarre, and Li Zheng's investigation reveals that her identity is entirely fabricated; her real name is Meng Yun, and the orphanage director Su Xiaowan is actually his deceased biological mother. Su Xiaowan was kidnapped and imprisoned by Li Daming back then, ultimately dying a tragic death in the mountain village. Meng Yun teams up with companions to bide her time for revenge, but after getting to know Li Zheng, she falls in love and decides to let him uncover the truth. After a confrontation, everyone calls the police, Li Daming is sentenced, and Meng Yun's sentence is reduced after entering prison. Years later, Meng Yun works at an anti-trafficking organization and reunites with Li Zheng, who has long been working there. The two look at each other, and all grievances settle into peace.
