orologio en Altadefinizione. Poirot, the Last Witness portrays Chilean photographer Luis Poirot (Santiago, 1940) as he opens his largely unpublished archive for the first time. Witness to key moments in Chile and Spain, from the Popular Unity (Unidad Popular) until now, we see him in action, in conversation, and in portrait sessions alongside figures such as Joan Manuel Serrat, Isabel Allende, and Pablo Larraín.
