Four schoolgirls in a Catholic girls’ high school – Unjoo, Soy, Eugene and Eun-young, swear their friendship with blood late one night at chapel within their school compound. The BFFs (best-friends-forever) promise each other that their bond will last through death, so much that they are even willing to die together.

However, there is more than meets the eye when one of them commits suicide one night… will the rest of the girls follow through with their promise and will their blood pledge of eternal friendship still hold?
