Five Australian couples who are struggling with their relationships meet each other on an island retreat.

The couples confront the problems they have been experiencing in the bedroom, in revealing discussions with sexologist, Dr Nikki Goldstein.

The couples have under three weeks to save their turbulent relationships. Some make progress, while others struggle, and one couple makes a sudden departure.

A camping trip brings the couples much closer together for better and for worse, far from their creature comforts. The distant location brings out some interesting interactions.

Dan makes a devastating confession to Lisa in the new apology booth. Other couples unload their lies and deceits to each other. The relationship coach hopes this will bring out any unresolved issues.
