Portugal, 1872. The Emperor of Brazil, Pedro II, travels to Porto and stays at the Grand Hotel du Louvre, owned by Maria Henriqueta de Mello Lemos e Alvelos. Today, the attempt to make a film about this episode becomes an invocation. Maria Henriqueta is with us. Memories, sounds, and sensations invade the screen and contribute to constructing an emotional geography of our invisible protagonist. It's a phantasmagoria of the senses. A good ghostly experience.
