A kid's imaginary friend turns out to be something wearing a human face. The mask doesn't grant powers, it reveals what was always there, waiting in the reflection. Nube movies understand that the real horror isn't the supernatural object, it's the loneliness that makes you want to put it on in the first place.
A new transfer student named Jun arrives at Nube's classroom carrying an unusual obsession: clowns. His isolation from other kids has left him with only one companion, a mysterious Pierre who exists solely within a mirror. When Pierre offers Jun a peculiar mask one midnight, everything spirals into chaos. The mask grants Jun strange powers, but wearing it transforms his behavior in increasingly unsettling ways. Accidents plague the school with mounting frequency and severity, each one more disturbing than the last. Nube senses something darker at work, something that feeds on Jun's loneliness and desperation for connection. The teacher must uncover the mask's true nature before Jun loses himself completely to its influence. Blending comedic moments with genuine supernatural dread, the story examines how isolation can make us vulnerable to dangerous forces. Nube's supernatural expertise gets tested as he races against time to save a boy caught between friendship and possession, between the comfort of a mirror's reflection and the terror of what that reflection truly is.
