Runtime: 86 minutes
Death Bell (Hangul: ??: ?? ????; RR: Gosa: Piui Junggangosa) is a 2008 South Korean film. The only Korean horror film released over the summer of 2008, it is the first feature by former music video director Chang (real name Yoon Hong-seung), who also co-wrote the screenplay. Death Bell stars Lee Beom-soo in his first horror film role, and K-pop singer Nam Gyu-ri in her acting debut. Set in a Korean high school, the film’s native title refers to gosa, the important midterm exams that all students are required to sit.
The film is set in a high school, where an elite group of twenty students—including rebellious heroine Kang Yi-na, her timid best friend Yoon Myong-hyo, and her suitor Kang Hyeon—are taking a special class for their college entrance exam. After Kang Yi-na is nearly strangled and another student throttled in the restroom, the classroom TV screen switches to an image of top-ranking student Hye-yeong trapped inside a fish tank that is slowly filling with water. A disembodied voice announces that her life depends on the exam questions he will set for them, and that a student will die for every question the class gets wrong.
