Excellent thriller based on the first novel by the Basque writer Dolores Redondo who subsequently wrote two more novels in what is called the "Baztán Trilogy" from the river of the Basque region where the stories take place. The film was produced by the German Peter Nadermann who had already brought the "Millennium Trilogy" to the screen. The film entrusted to director Fernando González Molina is well followed in the unfolding of the facts, involving the viewer in the complex and often obscure lives of the actors who are well supported. The almost always rainy setting gives the right "dark" touch to the narration.
A nice surprise that gives a European breath, as Millennium did, to a genre traditionally branded stars and stripes.
