Attack 13, directed by Taweewat Wantha, is a gripping supernatural horror-thriller set against the backdrop of high school volleyball and bullying. Bussaba—a ruthless volleyball team captain known for tormenting her teammates—is discovered dead, hung from a hoop in the school gym. Her abrupt, shocking suicide sends the school into chaos and deep horror. Meanwhile, Jindahra, a new transfer student, had directly challenged Bussaba’s tyranny. From the moment they clash, tension escalates dramatically. But Bussaba’s death isn’t the end—it’s only the beginning. Her vengeful spirit rises, haunting Jindahra and the rest of the team. As supernatural occurrences and dread intensify, the group races against time to uncover who summoned the ghostly bully—and how to stop her before they all fall victim to her wrath.
