Chatuchak Market, a renowned Thai landmark famous for its diverse animal vendors, becomes the center of a terrifying mystery. A series of horrific murders, bearing marks from an unknown, ferocious animal, coupled with a alarming rise in disappearances, grips the nation. Gina, a forensic scientist from the Thai Ministry of Justice, takes charge of the investigation personally when her only close friend, Noon, vanishes. Her desperate search for Noon leads her to uncover a dark secret hidden beneath Chatuchak, a truth far more sinister than anyone could have imagined.
