Amélie and Vincent meet as students at the Sorbonne at the end of the 1980s. It's love at first sight for both, but neither dares confess their feelings to the other. They agree to meet again, but Amélie is late. And in those few minutes, it's not just a date she misses out on, but her entire life.

Vincent and Amélie get swept up by life as it carries them toward fates they no longer control, jobs they didn't choose, marriages and relationships that become rocky. Life that takes them down paths, through doors, into hallways, for ten, twenty, or thirty years…

It is the story of two lives in parallel across the decades, the story of their relationships and careers, the story of chance encounters that bring them together again and again. Will chance give them the opportunity to get together?
