Hot shot young lawyer Bill Holden and his wife Becca move with their four-year-old daughter to the booming, gold-rush city of Shanghai. It is a place of opportunity and temptation, where fortunes are made and foreign marriages come apart in spectacular fashion. Bill's law firm houses the Holden family in Paradise Mansions - a luxury apartment block full of 'second wives': beautiful young women like JinJin Li, ex-school teacher, crossword addict, dedicated roller skater and the Holdens' neighbour. After Becca witnesses a near-tragedy, she returns temporarily to London with Holly - and Bill and JinJin are thrown together. Bill wants to be a better man than the millionaire who keeps JinJin Li as a second wife. Better than any man who cheats. Becca is his best friend. But in the end, can he give JinJin anything different - can he give her the love she deserves? And can he love his wife, too?
