The Intern is the Undercover Boss

Nobody in the office expects much from the quiet new intern, and that is exactly how she likes it. Behind the plain uniform is a woman with a hidden identity, and she has taken the job to dig into the truth behind a subsidiary company. As she moves through the workplace, she starts uncovering the schemes of people who never guessed she was watching them. Her steady, strategic counterattack turns the office into a battlefield where underestimating her becomes the costliest mistake.
