Three couples with varying degrees of success in both financial and romantic matters find they know relatively little about themselves or their respective partners. Successful stockbroker Dylan and his gorgeous wife, Charlotte, host a dinner party at their lavish apartment for two other pairs of friends, the recently separated Felix and Emilia and the seemingly happy Boris and Annette. Felix and Emilia had decided to attend the dinner as a couple, though each still has unresolved feelings towards the other. Meanwhile, Annette and Boris are on the verge of becoming engaged, though something seems to be preventing this from happening. As the night goes on, several topics are discussed — ranging from happy memories from the past to sexual relationships. At the height of the sex conversation, an impromptu bet is made that the two intact couples would not be able to identify their respective lovers by touching their naked bodies while blindfolded. Taking the bet, Boris, Annette, Dylan, and Charlotte strip down and discover more about themselves and each other than they ever intended.
