Twenty years ago, Jiang Rong, the richest woman, was resented by her friend Wang Xiuqin for not giving her daughter's special medicine to Wang's daughter. Believing her daughter would die every year, Wang Xiuqin set fire to Jiang Rong's house, took Jiang Rong's daughter Jiang Jiaojiao, and renamed her Wang Nian. Jiang Rong, unaware, adopted and cured her friend's daughter, renaming her Jiang Xun. Twenty years later, Wang Nian applied for a sales position at Jiang's company and met Jiang Xun. Her identity was exposed. To protect her position as the Jiang family's eldest daughter, Jiang Xun made things difficult for Wang Nian and Wang Xiuqin, unaware that Wang Xiuqin was her real mother. Feeling guilty, Wang Xiuqin endured Jiang Xun's mistreatment and went to jail to protect Wang Nian. Jiang Rong finally learned the truth and forgave Wang Xiuqin. Just as they were about to be reunited, Wang Xiuqin died in a car accident, completing her atonement with her life.
