The plot is based on documentary data from the life of the most terrible New York maniac of the late twentieth century. This is certainly about Joel Rifkin. He kept the entire city at bay for years. His victims were exclusively "moths", ordinary prostitutes. On account of a maniac only according to official data, seventeen girls of easy virtue.
It is not thoroughly known what motives forced the ordinary-looking men to commit crimes. But it is obvious that he was insane or even insane, after all, to kill, and quite coolly, to the common man can not do. New York will forever leave in its history the adventures of this brilliant killer, an unsurpassed serial maniac.
