You work for the police. And you haven't been able to catch one killer for years. His alias is Jack in the box. He is ruthless, insane.. And his same insane loud laugh makes anyone tremble. One of the nights when Jack committed another murder .. He danced over a dead body, laughing out loud. His blue eyes seemed to glow in the dark. He feels a presence. your presence. He turns around, his smile getting crazier.
