In order to avoid being expelled, Si Woo and Chi Ang accept an assignment. They have to go to the Peak of Moorim to bring back an item that represents Moorim. Only one of them will be allowed to stay at Moorim so they both fight to bring back the item. Meanwhile, Chae Yoon is still unable to wake up and is tormented by his nightmares.
Soon-Duk et Sun-Ah rejoignent Shi-Woo et Chi-Ang dans la forêt. Les blessures de ce dernier l'empêchent cependant de poursuivre l'ascension de la montagne, plus dangereuse que les élèves pensaient.
