Plot

After quitting her job as school librarian, Prudence Bell (Suzanne Pleshette) leaves New England for a vacation in Rome. On the ship over, she befriends Roberto Orlandi (Rossano Brazzi), a philandering middle-aged Italian. Upon their arrival in Rome, he introduces her to a countess who rents rooms in her villa to tourists. After finding employment at an American bookstore, Prudence encounters architectural student Don Porter (Troy Donahue), one of several Americans also rooming at the villa. Don is recovering from a failed relationship with a blonde temptress, Lyda (Angie Dickinson). Thus he keeps his distance at first. But he slowly sees Prudence as a refreshing curiosity with her adventurous outlook on life.
