Joe and Angela's marriage is already strained when they accept a dinner invitation from their upstairs neighbours, hoping for a distraction from unresolved tension at home. The neighbours turn out to be sexologists who practice radical sexual openness, an unexpected dynamic that quickly reshapes the evening.

What begins as awkward small talk spirals into territory neither couple anticipated, forcing Joe and Angela to confront whether the night has repaired their relationship or exposed cracks they can no longer ignore.
