TANDEM TELLS THE STORY OF A COUPLE, MAGDA AND HUGO, WHO HAVE BEEN LIVING TOGETHER FOR MANY YEARS. THEY EACH HAVE THEIR OWN WAY TO DERIVE SATISFACTION AND THEY ARE FAR FROM THE IDEAL OF THE HAPPY COUPLE WITH AN ACCOMPLISHED AND SYMMETRICAL SEXUALITY. WHILE MAGDA LIVES OUT HER ELABORATED FANTASIES ON HER OWN, HUGO’S LIBIDO IS ENTIRELY INVESTED IN HIS PASSION, MUSIC.
