Once Upon a Time, one of the first animated films made in Spain, is a free adaptation of the story Cinderella by Charles Perrault. It was directed by Cirici Pellicer, pseudonym of Jaime Baguña Gil, and obtained recognition for the best children's film at the Venice Film Festival.
In a dark and stormy night, Raimundo's car suffers a breakdown, so he and Gregorio, his chauffeur, must try to ask for shelter in the only nearby house, a sinister mansion, of those that seem inhabited by ghosts.
