High school sweethearts, Sarah and Warren, have grand plans for an adventurous future together, but when a misunderstanding causes them to part ways, they end up marrying other people.

When they meet again at sixty, their lives have been carved into very different shapes. Sarah lives outside New York; Warren lives in Boston. Sarah is divorced, Warren still married, and both have grown up children. When they reconnect, they feel the rekindled spark of love and desire – a spark that has been dead for so long. But are they willing to risk destroying all that they have built separately for the chance of a future together?
