Derykc Francisco Lombardi is the best peruvian director, I've seen his movies, and all of them are very good thrillers, but this one, keeps you in your seat from the beginning until the end. The movie keeps the nerve very well, and it reminds us the style of a Hitchcock movie, and of course he isn't Hitchcock, but the movie is good and is not like a bad movie of Brian de Palma who only copy Hitchcock's tricks but not the style. Lombardi won the golden seashell in San Sebastian Film Festival, I recommend this movie.
