Evelyn, a student, loses her badge during a dangerous lecture. The SSS-Class Ghost Professor announces that any student without a badge will be executed. As the search proceeds one by one, the professor then imposes 'The Dark Night,' banning all light and forbidding anyone from looking at another's face under penalty of death. In the resulting darkness, Evelyn is singled out by the professor, who demands to know who she is looking at, leaving her fate uncertain.
