Sleepless (2001 film)

Sleepless is a 2001 Italian thriller film directed by Dario Argento, starring Max von Sydow, Stefano Dionisi, Chiara Caselli, and Gabriele Lavia. The film centers around Moretti, a retired detective who is drawn back into investigating a series of murders that bear a striking resemblance to a case he worked on twenty years prior. The original killer, who targeted victims based on nursery rhymes, was never caught, and now it appears a copycat is at work.

Moretti, despite his age and health issues, teams up with a young man, Giacomo, whose mother was one of the original victims. Together, they must unravel the clues left by the killer, encountering numerous red herrings and increasingly dangerous situations. As they delve deeper into the investigation, they uncover a complex web of secrets and are forced to confront the dark past that continues to haunt the present. The film is noted for its graphic violence, stylish visuals, and suspenseful atmosphere, characteristic of Argento's giallo films.
