If you haven't seen the previous episodes, I strongly suggest you do. It explains the bound between the two protagonists. Once again Department Q delivers an emotional and strongly written police adventure. By now it's hard to imagine a movie in these series without the constant switch between past and present.

But it's still worth your time, even if you haven't seen the previous three films. I hope there will be more of these.
