Samjin Company English Class

"Abolish discrimination!"

In the mid 90s when sexual and academic discrimination was rampant (more than now), 3 young female office workers, Ja-young (Ko Asung), Yu-nah (Esom) and Bo-ram (Hye-soo Park) are shunned by their company and are given insignificant chores due to the fact that they only have high school diplomas.

When a company-wide memo goes around announcing that obtaining a 600 score in TOEIC could earn them a promotion, the trio and other high school grad female office workers enrol in English classes in the hope of finally advancing their careers. One day, Ja-young is sent to a factory in the country on an errand and by chance witnesses its waste water being poured into the river. Together with her 2 friends, she goes on a hunt to find irrefutable evidence that the company is into shady dealings.
