A ex-dancer has a heart problem and even with a transplant, he may still only have a few months to live. Time's spent looking at people/life in Paris from his balcony. His single mom sister moves in with her 3 kids to look after him.
Rémy is a young Parisian with an unskilled job. Mélanie is a young Parisienne who works in scientific research. Two depressive moods living in close proximity, but being unaware of each other. Will they ever meet?
