Two married couples in their late thirties live in Frankfurt-Oder. Although they are all friends, their relationship has become pretty staid of late. A typical evening spent watching holiday slides together makes it abundantly clear that both their friendship and their marriages have become nothing more than a dull routine. It's high time the cards in the game of life were reshuffled. Chris hosts a radio show; he and his second wife, Katrin, don't have an awful lot to say to each other - either in bed or anywhere else for that matter. Uwe spends almost all the hours that God gave him grafting at his snack bar, "Grill Point" and he neglects his wife, Ellen and the kids. No wonder that the lonely Ellen and Chris - who is just dying for something to happen - begin to get closer to each other. A chance meeting between the two of them leads to a secret love affair. However, their relationship is soon discovered and, before they know it, a whole new round in the game of life commences.
