Photographer Rachel and Parisian exotic dancer Rochelle live miles apart in London and Paris. Yet when they agree to swap apartments for six months, both find the excitement of discovering a new city full of surprises. You've been seduced by `Fifty Shades of Grey' and Sylvia Day's Crossfire series, now prepare to devour `The Exchange'. Rachel is bored in London, whilst over in Paris exotic dancer Rochelle is also weary of her life and unfulfilling relationship with fashion model Konrad. On arrival in Paris, Rachel visits Rochelle's strip club and feels the lure of exhibitionism for the first time. Whilst also succumbing to more than a passing interest in Konrad. Rochelle, meanwhile, falls in with a rich London crowd. For a while a string of random sexual adventures fills the void left by dancing. But enlightenment ultimately comes to Rochelle as she discovers that performing for an audience of one can be just as daring as dancing to a crowd.
