As Julie prepares to leave her husband Roger, she begins to play through a stack of recordings, each of which reminds her of events in their lives together. One of them is the song that was playing when she and Roger first met in a music store. Other songs remind her of their courtship, their marriage, their desire for a child, and the joys and sorrows that they have shared. A flood of memories comes back to her as she ponders their present problems and how they arose.
