Thongsuk is often bullied because of his nerdy look. Luckily he has Nam, his childhood friend, by his side. When they start college and get to know a new group of friends, Thongsuk has to face the hardest bullying than he could ever imagine. The friends, minus Thongsuk, then plan to spend the upcoming long weekend together on a small island, but Thongsuk surprises them, appearing uninvited. Angry with him, they lock Thongsuk in the closet at a deserted shrine. When they decide to free him, he is already gone. Where is he, in the night of Friday the 13th?
