A freelance cameraman travels around the world and wonders about the role of the images he creates. These images,as manifestations of his memories, are being commented upon by a woman friend, who reads his letters, and by a Japanese computer maniac, who rearranges the images on his synthesizer. Then a Filmmaker comes in and combines the letters, the comments, the images with each other and with some images of his own, to fashion film in the manner of a musical composition. In this way a fictional memory is born - yet Sunless is no fiction film.
