The writers, Manuel A. Meaños, Enrique Santos and Marcelo Menasche Discépolo, based the film on a strange story that circulated in
Buenos Aires around 1940. It told of an apparition in the form of a beautiful and enigmatic girl (Buschiazzo) who danced one night with the cashier (Arias) of a large commercial firm. She apparently had returned from the beyond, and would again fade into the shadows. ==Reception==
