Bitter Moon plot
"A kinky voyage with a full head of steam."
Nigel and Fiona, a respectable English couple, take a cruise to Istanbul to relaunch their marriage. On the ship they meet the disabled American writer Oscar and his stunning, sensual French wife Mimi. Oscar tells Nigel the story of their blistering passion that has brought him to the brink of collapse and even disabled him. Their relationship is mainly erotic, gradually pushing their boundaries of mental and physical pleasure into a game based on SM fantasies. Love and hate alternated more and more often, with both exploring the limits of cruelty towards each other. Nigel is shocked, but at the same time intrigued by Oscar and Mimi's story. Before they know it, Nigel and Fiona become pawns in the strange couple's tantalizing game.
