The film tells a story of a divorced couple trying to raise their young son. The story follows the boy for twelve years, from first grade at age 6 through 12th grade at age 17-18, and examines his relationship with his parents as he grows.
A young man and woman meet on a train in Europe, and wind up spending one evening together in Vienna. Unfortunately, both know that this will probably be their only night together.
Nine years later, Jesse travels across Europe giving readings from a book he wrote about the night he spent in Vienna with Celine. After his reading in Paris, Celine finds him, and they spend part of the day together before Jesse has to again leave for a flight. They are both in relationships now, and Jesse has a son, but as their strong feelings for each other start to return, both confess a longing for more.
