Manuel Luiz Vieira was the most important Madeira's film producer and director in the history of film in the archipelago, and also the most prestigious camera director in Portuguese film during the thirties. This film is the pearl of his pioneer work in Madeira Island and captures the most of his methodology: good stories taking the most of Madeira's natural scenery, and provoking the audience with some ironic and "double-sense" scenes. The film tells the story of an English girl travelling with her father, a botanic, and a guide from madeira in the deep mountains of the island. The girl has some mental disturbs and is always scaring about an attack from the native man, appearing as a half-man/half-monster. The rest you'e to see for yourself. There is a copy in Portuguese Cinemateca.
