This is a crime drama movie based on a book of the same Danish name (English: Till Death Do Us Apart, I think)
Very short runtime @ 1hr44m, watch this if you're in the mood for something different. I can name a similar 2014 crime/mystery thriller that you'd have watched, but if I name it to convince you to watch it, it might give the plot away.
The story revolves around a couple who, seemingly, have the perfect life until trust, morals, fidelity, etc. Are questioned. While it's not mindblowing, it's surely worth a one-time watch and there will be a couple diversions that you may not see coming.
Great cinematography (oooo, this movie looks amazing!) and sound design add to the value. Scores are underrating the film, so ignore them, and give it a shot.
