A vintage necklace. A long-hidden secret. A second chance for love. When costume designer Ariana Ricci leaves her groom at the altar, she seeks solace at the Palm Springs home of her great-aunt, a Texas-born Hollywood legend who began her career as an extra on the film Roman Holiday. While opening yellowed, 1950s letters postmarked Italy, Ariana discovers relics from her great-aunt's hidden past, including an intriguing necklace that Audrey Hepburn gave her during the filming of the movie. Aching for a fresh start and the chance to resolve an unfinished story, the two embark on a journey to the sun-dappled, elegant shores of Lake Como, Italy that will illuminate secrets of a bygone era and offer second chances to each of them-if they are bold enough to seize them.
