Wang Shuwei, president of Wang Group, conceals her identity and joins a subsidiary as an intern to secretly investigate its profit problems. Her carefully completed work is claimed by her colleague Zhou Xiaoxiao, who also steals the opportunity for a permanent position. Wang Shuwei stands by her principles and refuses to continue working for others for free. At a group banquet, Zhou Xiaoxiao insults Wang Shuwei, but Jiang Yuan, her childhood sweetheart, appears to defend her and uses his status as the young heir of Jiang Group to make Zhou back down. Zhou Xiaoxiao continues to make things difficult for Wang Shuwei, who remains clear-headed and upright. Eventually, Wang obtains evidence of Zhou's bribery and publicly exposes her during a company inspection. The violators are dealt with according to law, and the subsidiary's workplace culture is finally cleaned up.
