In grey, rainy 1920s England, Lotte and Rose, tired of their overbearing husbands, decide to rent a villa for a month in Portofino, Italy. To share the cost they invite two other, very different, women along– Lady caroline, a beautiful but bored socialite and crusty old Mrs. Fisher, who has an impeccable literary pedigree. All four long to escape from their trapped lives and the tranquil beauty of an Italian castle offers the rejuvenation they seek – albeit in ways they never imagined possible.
