When people come into contact with these cells, they turn into hideous and dripping creatures that can infect others at any time. Yeon-U, who is on a school trip to Seoul, is excited at the thought of getting closer to So-Yeon, a classmate whom he had a crush on. But for Yeon-U and his classmates, the trip soon turns into a nightmare.
