Nackt (2002)

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, naked.
