Death Bell

Death Bell (고사: 피의 중간고사, 2008) is a South Korean school horror-thriller you can watch online on iFILM. A group of top-performing students gets locked inside their prep school the night before college entrance exams. Then the intercom crackles to life: the best student, Hae-yeon, is sealed inside a tank slowly filling with water, and the voice on the speaker has a proposition — answer the exam questions correctly or she dies.

Wrong answers have consequences. The kills escalate, teachers scramble to decode who set this trap, and students start to wonder whether the school itself carries a darker secret. The film borrows the logic of the Korean education machine — the crushing pressure of university placement — and turns it into a body-count scenario, which gives it a harder edge than the usual classroom slasher.
