Su Baiyu, a genius hacker, got into a car accident while trying to save her best friend Ye Wangshu. When she woke up, her soul had traveled into Ye Wangshu’s body. Faced with the culprits who sought to destroy the Ye family — her hypocritical husband He Hongshan, vicious mother-in-law Zhao Guixiang, and the venomous Lin Mantang — Su Baiyu pretended to be mentally impaired. Using her hacking skills, she laid plans in secret. She teamed up with Lin Xubai, who was undercover beside He Hongshan. In the end, she sent all the villains to prison and found true love.
