This film is an Argentine adaptation of two short stories by American crime and suspense fiction writer Cornell Woolrich, who is credited under frequent pen name William Irish. Unlike most omnibus films, it does not feature a frame story.
This film was planned to incorporate three self-contained stories. The third part, based on the short story If I Should Die Before I Wake, was exited because the first two stories already constituted a feature length film, and the production company did not feel an audience would be willing to see a film longer than 120 minutes. It was released as stand-alone feature If I Should Die Before I Wake (1952).
This film was restored by the UCLA Film and Television Archive and presented in 2024 as part of the UCLA Film and Television Archive's Festival of Preservation. Golden Globe Foundation and the Film Noir Foundation funded the restoration project.
