Kim Sang-an, a cold-blooded loan shark.

When his sister, a school teacher, takes her own life after being relentlessly tormented by her students...

He becomes their new homeroom teacher to collect the "debt" of her life.

A debt collector who would crawl into the depths of hell to get what's owed, and students who are nothing short of demons.

A brutal "teacher-student" relationship begins now.
