Su Qing, a strong woman in overseas investment banking, returned to learn that her twin sister had been maliciously set up and framed by the company director together with three interns, burdened with a huge wrongful debt, and bullied by the workplace to the point of desperate falling from a building and remaining in a coma. To find out the truth and clear her sister's name, she hid her elite identity, disguised herself as a company cleaner, and lurked in dormancy. Faced with public bullying and humiliation from everyone, Su Qing no longer endured, publicly exposing the ironclad evidence of the director's fake accounts and framing, crushing all the company executives with top professional strength. She exposed the truth of the interns being used, purged the company's internal troubles, successfully seized power to reorganize the group, and made the evil director get what he deserved and end up in prison.
