In the White City (1983)

A Swiss sailor jumps ship in Lisbon, tired of the noisy engine room, the ship "a floating factory of crazy people." He rents a room and does little. He writes letters to his lover, describing the whiteness of the city, the solitude and the silence. He sends his love and emptiness; she replies with love and confusion. He sends movies from his 8mm camera. Then he becomes friendly with Rosa, a chambermaid, and soon it's a love affair. He continues to send letters and movies home. His Swiss lover is hurt and angry; she sends an ultimatum.
