Every school has a past that people want to be concealed. There are things that happened that people don't want to talk about. There are students whom people want to forget. And there are secrets waiting for the day…
ThirTEEN Terrors is a chilling Thai anthology series that peels back the hallowed halls of a seemingly ordinary school to reveal the dark, supernatural secrets lurking within. Each of the 13 self-contained episodes explores a different tale of teenage dread—from vengeful spirits and cursed objects to the cruel gossip that follows a bullied student into the afterlife. What ties these stories together is a raw, emotional core: the loneliness, fear, and quiet fury of youth. The series masterfully blends horror with poignant social commentary on school bullying, isolation, and the price of keeping secrets. Notably, one episode features a tender and tragic gay romance that stands out as a rare and heartfelt BL moment in the horror landscape. With a rotating cast of young Thai actors (many from the hit series Hormones), ThirTEEN Terrors offers both jump scares and lingering unease, making it a unique entry for fans of supernatural dramas and those seeking early LGBTQ+ representation in Thai television.
