A comedy which not only shows how a subtle twist of fate can affect the lives of total strangers, but which also tracks the lives of these seemingly unconnected individuals: a store clerk and her roommate, a barfly, an adulterer, and a few others--all of whom intersect over the course of one long Paris day. They interact with one another randomly, but every characters' chance encounter bears a consequence that will later become significant, ultimately culminating in a complex pattern of narrowly averted mishaps and barely grasped opportunities. And what finally emerges from the multiplicity of interactions is a deceptively simple love story.
