Dana (Foyt), a young American woman, is told a story of lost love by a stranger while on vacation in Jerusalem. The stranger clearly pines for her former American lover but both subsequently married different partners. After a trip to Paris with her fiancÃ©e Dana has a chance encounter with a British man, Sean (Dillane), at the White Cliffs of Dover. Although both are in relationships, they develop passionate feelings for each other that threaten to destroy their established relationships. Dana begins to reflect that Sean is her true love and feels as if her situation will reflect that of the sad stranger in Jerusalem if she does not act.
