Who Is You? is a Portuguese film, written and directed by João Botelho, from the adaptation of the book Frei Luís de Sousa de Almeida Garrett.Despite some changes in the unfolding of history, the essential plot remains.The scenarios of the film, with little light and always being closed enclosures are also, in themselves, part of the history, since they intend to isolate more and more the characters, to the point of leaving them "in a dead end".
