Lin Wan, a newcomer who has just entered Hengyu Media, is unwilling to submit to the endless workplace squeezing and achievement plundering of team leader Zhang Man, facing bullying with a sober and resolute attitude. Shen Chen, the headquarters inspector hiding in the department's undercover visit, secretly hands her clues, and the two form an alliance. Layer by layer, they peel off the cocoon, successively exposing the chaos of plagiarism, false reporting, and corruption, and ferreting out the backstage backer, Vice President Zhang Lei. The two join hands to collect complete evidence, sweep away the company's bad atmosphere, and establish new rules for a fair workplace. In the morning and evening twilight where they stand side by side against the haze, feelings quietly breed, and the youths use courage as a blade, ultimately trading for a fresh breeze in the workplace.
