When a town is plagued by a grisly serial killer, the only person capable of catching the murderer is retired police chief Ulisse Moretti (Max von Sydow). Since Moretti battles severe insomnia, the case isn't the only thing keeping him up at night. But if he can keep his wits about him, he just might be able to stop a madman on the loose. Italian auteur Dario Argento directs this stylish thriller that co-stars Stefano Dionisi and Chiara Caselli.
