Substitute bride Wen Wanwan was abandoned by the ruthless CEO Gu Yesen. After she became pregnant, she was even tricked into having an abortion, and she fled with her injuries. Five years later, she became the anonymous hacker "Lone Star", and her 5-year-old son Gu Nianchen beside her was a real genius hacker. The cute baby hacked into his father's security system and forced Gu Yesen to find his mother in the name of "cooperation". When father and son reunited, Gu Yeshen discovered that his son could crack all his passwords in one second, and Wen Wanwan already had a gentle fiancé. The cute baby's revenge plan: to make his father fall in love with his mother, and then let him delete his memory with his own hands - this is the real murder.
