Lisbon, a normal day in one of the typical narrow streets of the capital of Portugal. In a small house, in a dirty little street, in a dark corner of the city lives a poor blind beggar, which earns his living through the selling of useless trinkets. The only curious situation is that the blind man keeps all his savings in a little black box donated to him by the government. It is through this box that the poor man proves his visual handicap. And it is this same BOX (a CAIXA) that is envied by all the blind man´s lazy neighbours who are jealous of the little money that is given to the poor man. The life on this (intentionally) excessive dramatic small world is suddenly turned upside down when someone steals the BOX of the blind man unleashing a chain of events that will have a surprising end.

The film was to be a documentary, but evolved during production to a fictional film. It nevertheless adheres strictly to the poems and letters exchanged by two of the most outstanding names of the Modernist Movement, Fernando Pessoa (in Lisbon) and Mário de Sá-Carneiro (in Paris). Their endless conversation was dramatically and suddenly terminated.

A woman translates the front page of H.P. Lovecraft's book “The Silver Key”. Her husband, a journalist, listens. The book describes the conflicts between the real and the imaginary, and tells how Randolph Carter, the film's character, leaves everyday life in search of his childhood dreams.
