 Otis (Dominique Pinon) is a live-in lift operator who has never set foot outside his elevator. He is secretly in love with K (Claude Lavallee), a junior typist who is afraid of elevators and has never set foot in one. Each morning, as K climbs the 20 flights of stairs to her typing pool, Otis does his best to parallel her ascent. He subtly influences the demands of his many passengers to catch glimpses of his beloved. K s only pleasure is typing her dreams on her lunch breaks. Everyday they each go about their routines with quiet dedication. But this routine is about to change.
