An American couple, Belle and Wren, have traveled to Greece on an anniversary trip, hoping to resurrect their stumbling marriage. But at a party along the Attic coast they meet several guests who offer unexpected digressions, one being a cruise around the age-layered Aegean Sea. Circumstances lead Belle to take the cruise, while Wren, alone in Athens for a few days, chooses to visit Delphi and its oracle. Told through their alternating views, both experience life-altering encounters which support their growing beliefs that their marriage can make neither happy and fulfillment lies in other directions.
