Happenstance (1997)

Synopsis
After a series of short films, writer/director Laurent Firode made his feature-length debut with this tale of coincidence, chance, and fate inspired by a variation of the chaos theory, which supposes that if a butterfly beats its wings in one part of the world, it could theoretically cause a full-fledged storm thousands of miles away. Firode applies this theory to a disparate group of Parisians, opening with a young retail worker, Irene (Audrey Tautou), reading her horoscope on the train to work one morning. At the store, Irene has to deal with an elderly woman (Francoise Bertin) who wants to return a broken coffeemaker; as if that weren't enough, the dissatisfied octogenarian consumer has to put up with her impudent grandson, Luc (Eric Feldman). Amidst all the seemingly unrelated human activities in the film, cockroaches, bird droppings, and changes in the weather all conspire to bring the characters together -- or drive them apart, as the case may be. ~ Michael Hastings, All Movie Guide
