'Night Study' will be a zombie movie that takes place at an education center where students in their junior year of high school are studying overnight to prepare for the college entrance exams in 100 days.  The movie centers on a one night struggle when the students suddenly come face to face with zombies during their precious prep time. 

If Siwan accepts the part, he would play a male student named Haeng Sung who is accompanied by his best friend throughout the movie.
