This story is about 4 students who are studying at St. Martha's Academy. One day in the Science laboratory, the teachers observe a student who is emotionless and her physical look is so pale, her vains are visible and her eyes are full white, some believe that the student is possessed, but we believe that she is infected. Infected by an anonymous virus that our Science professors invented. Until the nightmare happens, the virus is spread quickly in the Academy and also outside the campus, which means in the city. Some of the survivors stayed alive by locking themselves in some vacant rooms, but some did not make it.
