Four Ice Cubes

There were four of them. Eight years ago they studied at an elite lyceum, considered one another best friends, and felt like kings of life. After school, their paths diverged, and they almost forgot what they did when they were kids… But one day, on a cold, rainy autumn afternoon, each of these four meets a strange girl dressed in black—more like a ghost than a living person. She says she came from hell and brings retribution for their mistakes and crimes. Could something like that really be possible? Do ghosts exist? Or is this crazy game run by a person?
