Death Bell: Their Final Exams Will Be Their Final Exam

Being at the top of the class is a mixed bag at Chang Ahn High School. Straight A's may get you into college but here they could also get you drowned in a fish tank or tossed to death in a dryer if your fellow students don't figure out that puzzle on the chalkboard in time. Death Bell's midterms of murder have something to do with a dead student whose killer remains at large. Since someone at C.A.H.S. did it, heads are going to roll until that someone confesses (and asks for an apology). Scholarship student Yi-na (Nam Gyu-ri) figures this out soon enough. Why not? She was buddy-buddy with the victim and knows what it means to study hard, only to land in fifth place on the honor roll. (That ranking gives her some breathing space when the serial killer is working down the list.) But Yi-na also knows how to have a good time, thanks to her friendship with Hyeon (Kim Bun), the school prankster who sidelines as a DJ and would definitely get better grades if he applied himself. Head teacher Mr. Hwang (Lee Beom-su) sure believes in Hyeon; Ms. Choi (Yoon Jeong-hee)? Not so much. But then she doesn't seem to believe in anyone except director Yoon Hong-seung who's giving her plenty of screen time to scream in his K-horror torture porn.
