The documentary has been built as a journey back to the places photographed and filmed by Buñuel to see them from now, but also a trip down the memory of people who participated in the shooting, like his son Juan Luis Buñuel or the actors Rosenda Monteros, Pilar Pellicer and Ignacio López Tarso, plus photographers, artists, friends, collaborators and filmmakers that we can see here and and hear their only witness.
