An Accidental Expert Walks Into Suneung Chaos
The film follows Maeng Bo Ram (Lee Sun Bin), a Korean language teacher from a small provincial town who’s mistakenly recruited onto the committee responsible for writing Korea’s College Scholastic Ability Test (CSAT), also known as the Suneung — one of the most high-stakes exams in the country. A recruitment error mixes her up with another woman of the same name who was actually the intended expert, and Bo Ram finds herself locked inside a facility sealed off for 40 days with zero room for error.

What the Trailer Reveals
The newly released trailer opens on CSAT day itself, with the entire country on edge — flights grounded, stock market opening delayed — before flashing back 40 days to the pandemonium behind closed doors. Bo Ram arrives cheerful and clueless, gets thrown into intense meetings with veteran question-setters, and somehow holds her own amid raised voices and heated debates. It ends on a warmer note, with committee head Park Kyung Tae giving her an approving thumbs-up.
