Nackt is the story of three couples, one of which just broke up, one that seems to be about to and one perfectly okay. They are all friends and from time to time they gather to talk about everything.
One time they gather for dinner at the second couple's "mansion" - the husband became rich with his business. We see each couple as they prepare themselves for the party and learn a lot about their relationships.
At the dinner they get to talking about recognizing each other's peer with closed eyes and decide to try it (thus the title "Nackt"=naked in German). Nothing more to be spoiled by me. Watch it.
We get really deep into the relationships of these young couples, their love, their problems and the way they try to overcome them. The movie got us thinking and probably will get you as it doesn't stick to the surface but lets its characters talk about every minor detail.
The actors are quite famous in Germany and deliver a good performance. I give it 8 out of 10.
