Juri maintains a carefully curated Instagram presence with millions of devoted followers, but her offline existence tells a starkly different story—one shadowed by an obsessive ex-boyfriend, a possessive copycat admirer, and the fractured remnants of a friendship with her former best friend Na-yeon. As her digital influence grows, so does the hostility surrounding her, driving Juri deeper into the solace of her online persona and away from the messy complications of real relationships. Her retreat into the digital world is interrupted violently when she awakens in a dark basement as a kidnapping victim, forced to navigate her nightmare alongside another captive who appears equally trapped. With an unseen pursuer closing in, Juri and her fellow hostage must uncover the motivations behind their abduction while fighting for any chance of escape.
