When a young American (Amanda Seyfried) travels to the city of Verona, home of the star-crossed lover Juliet Capulet of Romeo and Juliet fame, she joins a group of volunteers who respond to letters to Juliet seeking advice about love. After answering one letter dated 1957, she inspires its author (Vanessa Redgrave) to travel to Italy in search of her long-lost love, and sets off a chain of events that will bring a love into both their lives unlike anything they ever imagined.
