Cuando Los Ángeles Duermen (or When Angels Sleep for the English title) is a simple but entertaining Spanish movie about how fast things can turn from rather normal to complete chaos. It's not really a horror movie though, more a drama/thriller. Not a big cast as the whole story is more about two main characters, one that tries to convince the other he's not a bad person, and the other being completely paranoid. Well acted from both of them, as the rest of the small cast. There are no slow moments in this movie, there is some light suspense throughout the entire story and it's shot decently so definitely worth a watch.
