Frederick Winterbourne is hanging out around Vevay like a hipster at a coffee shop, bored and unimpressed with the regulars. Will someone or something new and exciting come along?
Winterbourne embarks on an acquaintance (let's be honest, they're never really that tight) with the young, attractive, and vivacious American, Daisy Miller. Though it's never made completely explicit, Winterbourne undoubtedly has eyes for Daisy and imagines they might have a future together. Maybe old Winterbourne is about to have his world rocked. . .
Gossip about Daisy and her inappropriate romantic antics with the Italian lawyer Mr. Giovanelli swirls around Rome. Daisy's frustrated because her little inroads into the world of high-class expats are getting blocked left and right. Winterbourne's frustrated because, in his opinion, Daisy keeps acting out of line. Can't he see that that's why he likes her in the first place? Great, now we're frustrated, too.
Daisy ignores Winterbourne and he begins to believe that she's going to marry herself to Giovanelli. All his hopes and dreams of Mrs. Daisy Winterbourne seem like they'll never be.
Daisy contracts malaria and dies. Winterbourne realizes she loved him all along and perhaps he should have made a move. Forget about not buying stocks in Apple years ago—this is some serious regret.
