Business as usual ... except when you get caught doing something you are not allowed to do. Usually you then have to suffer the consequences. Unless you decide that someone could sacrifice themselves to save others. And that is the overall premise here. Although as you can imagine no one is willing to take the fall like that.
So this drama/thriller is playing out in one location and therefor has to have something more going for it, twists and character traits, people clashing with each other. And overall the tension is kept throughout with moods swinging, opinions changing and views deceived. It works nicely, but it's not the very best out there. Still to be able to watch this so closely to its release in Spain in another country (also on Netflix) is kind of nice
