She joined to make tests, not become a prisoner.
Ms. Maeng, a small-town teacher, unexpectedly joins the team responsible for creating South Korea’s most important exam: the College Scholastic Ability Test. She thought it would be all about academic prestige and scholarly debate but instead finds herself locked away under spy-level security, her phone confiscated and surrounded by office politics. Can this unlikely underdog turn test stress into test success, or just test everyone's patience?

Trivia, insights & behind the scenes
The CSAT literally stops South Korea for a day — flights are grounded, stock markets delayed, police escort late students. The film weaponizes this national obsession for comedy.
Writer-director Lee Yong-jae based the sealed-facility premise on real CSAT question development, where actual educators are isolated for weeks with no outside contact.
