The film was inspired by the letters exchanged between two leading Portuguese poets, Sophia de Mello Breyner Andresen and Jorge de Sena, during the exile of the latter (1957-78). Through their poetry and their letters, the film builds a dialogue between longing and belonging, the "desire to fill years of distance with hours of conversation". At the same time, it establishes a correspondence with our own lives fictionalized under the ties and entanglements that hold us together.
