One year has passed since "The Witness." Now, an upgraded and intensified kidnapping and confinement special, "The Fifth Victim," arrives! The setting is an eerie abandoned school. Crumbling walls, broken chairs, an abandoned recorder with no owner... This building has transformed into a forgotten space due to a past incident. A psychological, closed-room suspense thriller begins here. The truth behind an event from five years ago surfaces, as teenagers cornered by circumstances continue to resist. And lurking over them—an unseen, threatening presence. As mystery after mystery unravels, fear steadily deepens. This release, Side.A "Origin—Memory," portrays the beginning of the story.
