A classic whodunit mystery, as the characters go about their lives in 1920s Italy, when Benito Mussolini's brand of fascism was on the rise.
　　Set in the 1920s on the Italian Riviera, the series stars Natascha McElhone (Ronin, Californication, Halo) as Bella Ainsworth, the daughter of a wealthy industrialist who moves to Italy to set up a quintessentially British hotel in the breathtakingly beautiful town of Portofino. Mark Umbers (Home Fires, Mistresses, Collateral) plays Bella’s charming but dangerous aristocratic husband, Cecil, and Anna Chancellor (Four Weddings and a Funeral, The Hour, Mapp & Lucia) costars as Lady Latchmere, the hotel’s most influential and hard-to-please guest.

　　本剧基于Frederick Forsyth的同名小说和1973年同名改编电影创作。
