En Route To

The film touches on themes of teenage pregnancy, parental abandonment, abusive teachers, and suicide.

It follows Yoon-ji, a first-year high school student who becomes pregnant after an affair with her married homeroom teacher. Following the pregnancy, her teacher suddenly disappears without notice. Despite wanting a family, Yoon-ji decides to get an abortion, believing that this might bring back the return of her teacher.

Without money, Yoon-ji is brought to steal the savings of her roommate Kyeong-seon to purchase illegal abortion pills in order to terminate her pregnancy. While this initially causes strife with Kyeong-seon, who has been illegally selling vape cartridges to classmates, she soon starts to help Yoon-ji when she realizes the reason for Yoon-ji's theft.
