An administrative mix-up. A sealed-off facility. And Korea’s most nerve-wracking national exam. The new trailer for “Ugly Duckling Ms. Maeng” promises chaos, comedy, and Lee Sun Bin caught right in the middle of it.

### 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](https://en.wikipedia.org/wiki/College_Scholastic_Ability_Test) — 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.

### Why This Premise Hits Home?

The CSAT is a genuine cultural phenomenon in Korea — flights get rescheduled, businesses adjust opening hours, and roughly 500,000 students’ futures hinge on a single day. Turning the secretive, high-pressure process of writing that exam into a comedy gives the film built-in tension and plenty of room for absurd situational humor.
