Actress Shen Yue transmigrates into an 1980s novel as the real heiress destined to be cannon fodder. Swapped at birth by a nanny, the original Shen Yue grew up in the countryside, where she was forced into a marriage by a village thug, bullied by the fake heiress, and ultimately met a tragic death. After transmigrating, Shen Yue refuses to become obsessed with romance and seizes the ancestral spiritual spring and magical space cheat for herself. She beats up the local bullies and heads to the capital to care for her second older brother, who was injured at work. On the train, she helps solve a criminal case and receives official recognition. Her casual design improvements earn her a position as chief designer at a clothing factory. In the capital, she uses the spiritual spring to help her brother recover and get promoted, starts an underwear brand with her neighbor Wang Linghua, recruits the rebellious Lin Wen to handle sales, and establishes the Yiren Society retail stores. Despite misunderstandings with the aloof factory director Lu Jingchuan, she stays focused on making money, competes in the national fashion design competition, and embarks on her triumphant rise in the 1980s.
