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.
