In this modern twist on the classic romantic comedy genre, warehouse employee Rémy (François Civil) and research assistant Mélanie (Ana Girardot) have never met, but they live parallel lives: they reside in neighboring apartment buildings, ride the same subway route, and are troubled by bouts of insomnia and depression. As they stumble through psychotherapy, dating apps, fainting spells, and family visits, the seemingly star-crossed duo orbit around each other but remain just out of reach. Director Cedric Klapisch spins a delicate “what-if” exploration of modern relationships that is funny and moving.
