Synopsis
The film is set at a sophisticated high-rise apartment complex. Se-jin lives in this glamorous yet cold space. One night, Se-jin witnesses the lights in units across from hers go out all at once. Carefully watching the units from that night, she comes to recognize a certain pattern that those lights go out at exactly 9:56 PM. This incomprehensible phenomenon spreads across other units over the time, intensifying fear in the process. In a movie based on a cartoon by Gang Full and directed by Korea's master horror filmmaker Ahn Byung-gi, the audience will see a welcome return to silver screen by KO So-young, one of Korea\'s leading actresses after a long time.
