When the body of American journalist Gregory Moore (Jean Sorel, Perversion Story) is discovered in the beautiful Malá Strana area of Prague, the body is moved to the morgue for an autopsy. Only thing is, Gregory is still alive and has been paralyzed in a death-like state. As the ultimate deadline draws near, Gregory’s mind races to recall why this happened to him and who is behind a spat of kidnappings of gorgeous local women, including his girlfriend Mira (Barbara Bach, The Unseen).  Aldo Lado’s remarkable film is an atmospheric delight that boasts an incredible score from the maestro himself, Ennio Morricone (The Good, The Bad & The Ugly), and more than deserves it’s reputation as one of the finest examples of the giallo genre. 88 Films are proud to present this stone cold classic of Italian cinema, in pristine 4K UHD with Dolby Vision and a bevy of archive and new Special Features.
