Freddie throws Hesters life in turmoil, as their erotic relationship leaves her emotionally stranded and physically isolated. For Freddie, that tumultuous mix of fear and excitement that was once in his life seems to be no longer present.The majority of the film takes place during one day in Hesters flat, a day on which she has decided to commit suicide. Her attempt fails and as she recovers, the story of her affair and her married life is played out in a mosaic of short and sporadic flashbacks. We soon discover the constraints of Hesters comfortable marriage, which is affectionate but without sexual passion. ........
